sophon-demo Environmental Installation Guide

Contents

The environments Sophon Demo relies on include the TPU-NNTC and TPU-MLIR environments for compiling and quantifying the models, the development environment for compiling C++ programs, and the runtime environment for deploying the programs.

1 TPU-MLIR Environmental Installation

If you are using BM1684X, it is recommended to use TPU-MLIR to compile BModel. Usually, you need to install TPU-MLIR environment on an x86 host with Ubuntu 16.04/18.04/20.04 installed and running memory of 12GB or more. Here are the installation steps for TPU-MLIR environment:

  1. Installation of Docker

    If you already have docker installed, skip this section.

    # If your docker environment is broken, uninstall docker first
sudo apt-get remove docker docker.io containerd runc

# install dependencies
sudo apt-get update
sudo apt-get install \
        ca-certificates \
        curl \
        gnupg \
        lsb-release

# get keyrings
sudo mkdir -p /etc/apt/keyrings
curl -fsSL \
    https://download.docker.com/linux/ubuntu/gpg | \
    gpg --dearmor -o docker.gpg && \
    sudo mv -f docker.gpg /etc/apt/keyrings/

# add docker software source
echo \
    "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
    https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | \
    sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# install docker
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

# In docker, commands can be executed without root privileges
# Create docker user group,if there is already a docker user group, it will raise an error,this error can be ignored
sudo groupadd docker
# Add the current user to the docker group
sudo gpasswd -a ${USER} docker
# Switch current session to new group or re-login to restart X session
newgrp docker​

    Note：You need to logout the system and then log back in, and then you can use docker without sudo.

  2. Create and Enter Docker

    The docker used by TPU-MLIR is sophgo/tpuc_dev:latest, the docker image and tpu-mlir have a binding relationship, in a few cases it is possible that tpu-mlir is updated and a new image is needed.

    docker pull sophgo/tpuc_dev:latest
# Here will map current directory to /workspace directory in docker, users need to map the demo directory to docker according to the actual situation
# Myname is just an example of a name, please specify it as the name of the container you want
docker run --privileged --name myname --network host -v $PWD/..:/workspace -p 8001:8001 -it sophgo/tpuc_dev:latest
# Now, you are already in docker, and in the /workspace directory

  3. Install TPU-MLIR

    Currently supported 3 methods to install:

    (1)Download and install directly from pypi:

    pip install tpu_mlir

    (2)Get newest tpu_mlir-*-py3-none-any.whl from TPU-MLIR Github, then install with pip:

    pip install tpu_mlir-*-py3-none-any.whl

    TPU-MLIR requires different dependencies when processing models of different frameworks. For model files generated by onnx or torch, use the following command to install additional dependency environments:

    pip install tpu_mlir[onnx]
pip install tpu_mlir[torch]

    There are 5 config currently supported: onnx, torch, tensorflow, caffe, paddle. You can install multiple dependency config in one command, or use all to install all dependencies:

    pip install tpu_mlir[onnx,torch,caffe]
pip install tpu_mlir[all]

    (3)If you attained tpu-mlir release build, such as tpu-mlir_${version}-${hash}-${date}.tar.gz, here are configurations:

    # uninstall tpu_mlir if you installed it before.
pip uninstall tpu_mlir

tar xvf tpu-mlir_${version}-${hash}-${date}.tar.gz
cd tpu-mlir_${version}-${hash}-${date}
source envsetup.sh #configure environment variables.

It is recommended that TPU-MLIR's docker image is only for compiling and quantifying the model, please compile and run the program in the development and runtime environment. For more tutorials on TPU-MLIR, please refer to the "TPU-MLIR Quick Start" and the "TPU-MLIR Technical Reference Manual" on the official website of Sophgo.

2 TPU-NNTC Environmental Installation

Attention, TPU-NNTC has stopped maintenance. If there are any issues with using TPU-NNTC, we recommend using TPU-MLIR.

If you are using BM1684, it is recommended to use TPU-NNTC to compile BModel. Usually, you need to install TPU-NNTC environment on an x86 host with Ubuntu 16.04/18.04/20.04 installed and running memory of 12GB or more. Here are the installation steps for TPU-NNTC environment:

  1. Installation of Docker

    If you already have docker installed, skip this section.

    # Install docker
sudo apt-get install docker.io
# In docker, commands can be executed without root privileges
# Create docker user group,if there is already a docker user group, it will raise an error,this error can be ignored
sudo groupadd docker
# Add the current user to the docker group
sudo gpasswd -a ${USER} docker
# Switch current session to new group or re-login to restart X session
newgrp docker​

    Note：You need to logout the system and then log back in, and then you can use docker without sudo.

  2. Download and Unzip TPU-NNTC

    Download the Compatible TPU-NNTC package from the official website of Sophgo and unzip it, the package is named in the format tpu-nntc_vx.y.z-hash-date.tar.gz, where x.y.z indicates the version number.

    mkdir tpu-nntc
# Unzip the package to tpu-nntc
tar zxvf tpu-nntc_vx.y.z-<hash>-<date>.tar.gz --strip-components=1 -C tpu-nntc

  3. Create and Enter Docker

    The docker used by TPU-NNTC is sophgo/tpuc_dev:latest, the docker image and tpu-nntc have a binding relationship, in a few cases it is possible that tpu-nntc is updated and a new image is needed.

    cd tpu-nntc
# Enter docker, if the current system does not have the corresponding image, it will automatically download from docker hub
# Here will map tpu-nntc's higher level directory to /workspace directory in docker, users need to map the demo directory to docker according to the actual situation
# 8001 to 8001 port mapping is used here, which will be used later in the ufw visualization tool
# If the port is already occupied, please replace it with another unoccupied port, and adjust it later as needed
docker run --privileged --name myname -v $PWD/..:/workspace -p 8001:8001 -it sophgo/tpuc_dev:v2.1
# Now, you are already in docker, and in the /workspace directory
# Then, initializing the software environment
cd /workspace/tpu-nntc
source scripts/envsetup.sh

This image is only for compiling and quantifying the model, please compile and run the program in the development and runtime environment. For more tutorials on TPU-NNTC, please refer to the "TPU-NNTC Quick Start Guide" and the "TPU-NNTC Development Reference Manual" on the official website of Sophgo.

3 x86 PCIe Platform Development and Runtime Environment Construction

If you have installed a PCIe accelerator card on an x86 platform, the development environment and runtime environment can be the same, and you can build the development and runtime environment directly on the host computer.

Attention： mlir's docker is for compiling bmodel, it is not recommended to use it as runtime environment. If you need to set up a docker test environment on the host, please refer to "Chapter 6 - Using test environment by Docker" in LIBSOPHON_User_Guide.pdf.

3.1 Installation of libsophon

Download the Compatible SOPHONSDK from the official website of Sophgo, libsophon installation package is under the directory libsophon_{date}_{time}, which includes:

  • sophon-driver_x.y.z_amd64.deb
  • sophon-libsophon_x.y.z_amd64.deb
  • sophon-libsophon-dev_x.y.z_amd64.deb

Regarding the above three installation packages: x.y.z indicates the version number; sophon-driver contains the PCIe accelerator card driver; sophon-libsophon contains the runtime environment (library files, tools, etc.); and sophon-libsophon-dev contains the development environment (header files, etc.). If you are only installing on a deployment environment, you do not need to install sophon-libsophon-dev.

# Install the dependency library, you only need to execute once
sudo apt install dkms libncurses5
# Install libsophon
sudo dpkg -i sophon-*amd64.deb
# You can use a command such as bm-smi after execute the following command in the terminal, or log out and log in to the current user
source /etc/profile

For more information on libsophon, please refer to "LIBSOPHON Manual".

3.2 Installation of sophon-ffmpeg and sophon-opencv

Download the Compatible SOPHONSDK from the official website of Sophgo, sophon-mw installation package is under the directory sophon-mw_{date}_{time}, which includes:

  • sophon-mw-sophon-ffmpeg_x.y.z_amd64.deb
  • sophon-mw-sophon-ffmpeg-dev_x.y.z_amd64.deb
  • sophon-mw-sophon-opencv_x.y.z_amd64.deb
  • sophon-mw-sophon-opencv-dev_x.y.z_amd64.deb

Regarding the above packages: x.y.z indicates the version number; sophon-ffmpeg/sophon-opencv contains the runtime environment of ffmpeg/opencv(library files, tools, etc.); and sophon-ffmpeg-dev/sophon-opencv-dev contains the development environment (header files, pkgconfig, cmake, etc.). If you are only installing on a deployment environment, you do not need to install sophon-ffmpeg-dev/sophon-opencv-dev.

sophon-mw-sophon-ffmpeg depends on the sophon-libsophon package, while sophon-mw-sophon-opencv depends on sophon-mw-sophon-ffmpeg, so you must install libsophon first, then sophon-mw-sophon-ffmpeg, and finally install sophon-mw-sophon-opencv.

If the libstdc++ library used in the runtime environment uses an older version of the ABI interface prior to GCC 5.1 (typical with CENTOS systems), please use the sophon-mw-sophon-opencv-abi0 related installation package.

# Install sophon-ffmpeg
sudo dpkg -i sophon-mw-sophon-ffmpeg_*amd64.deb sophon-mw-sophon-ffmpeg-dev_*amd64.deb
# Install sophon-opencv
sudo dpkg -i sophon-mw-sophon-opencv_*amd64.deb sophon-mw-sophon-opencv-dev_*amd64.deb
# Execute the following command in the terminal, or log out and log in to the current user
source /etc/profile

For more information on libsophon, please refer to "MULTIMEDIA User Manual", "Multimedia Development Reference Manual".

3.3 Compilation and Installation of sophon-sail

If the demo depends on sophon-sail, you need to compile and install sophon-sail, otherwise you can skip this section. You need to download the Compatible SOPHONSDK from the official website of Sophgo, under the directory sophon-sail_{date}_{time}, the package is named in the format sophon-sail_x.y.z.tar.gz, where x.y.z indicates the version number. You can open the user manual provided in the sophon-sail compressed package (named sophon-sail_en.pdf), refer to the compilation and installation guide chapter, and select the mode you need (C++/Python, PCIE MODE) for installation.

4 SoC Platform Development and Runtime Environment Construction

For SoC platforms, the SophonSDK (>=v22.09.02) has been installed with the corresponding libsophon, sophon-opencv and sophon-ffmpeg runtime library packages integrated inside, located under /opt/sophon/, which can be used directly for the runtime environment. Programs are usually cross-compiled on x86 hosts to enable them to run on SoC platforms. SophonSDK firmware refresh methods can be found in the FAQ document.

4.1 Cross-compiling Environment Construction

You need to build a cross-compilation environment on an x86 host using SOPHONSDK and package the header and library files that the program depends on into the soc-sdk directory.

  1. Build a cross-compilation environment, here we provide two methods:

    (1)Install cross-compilation toolchain by apt:

    If your environment's libc version is the same as target SoC platform, you can use following commands to install:

    sudo apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu

    uninstall:

    sudo apt remove cpp-*-aarch64-linux-gnu

    If your environment doesn't qualify conditions above, we recommend you method (2).

    (2)Using docker image：

    Please note that you should not mix the stream_dev image below with the tpuc_dev image for model compilation.

    Download the ubuntu20.04 image through dfss:

    pip3 install dfss
python3 -m dfss --url=open@sophgo.com:sophon-demo/common/docker/stream_dev.tar # ubuntu 20.04, gcc-9

    If your target SoC is BM1688/CV186AH, SDK version >= 1.9(use command bm_version to check), you should use this docker image:

    python3 -m dfss --url=open@sophgo.com:sophon-demo/common/docker/stream_dev_22.04.tar # ubuntu 22.04, gcc-11

    If you're using Docker for the first time, you can execute the following commands to install and configure it (only for the first-time setup):

    sudo apt install docker.io
sudo systemctl start docker
sudo systemctl enable docker
sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

    Load the image from the downloaded image directory:

    docker load -i stream_dev.tar

    You can check the loaded image using docker images, which defaults to stream_dev:latest.

    Create a container:

    docker run --privileged --name stream_dev -v $PWD:/workspace  -it stream_dev:latest
# stream_dev is just an example name; please specify your own container name.

    The workspace directory in the container will be mounted to the directory of the host machine where you ran docker run. You can use this container to compile the project.

    Note: this docker image came from sophon-stream。

  2. Package libsophon

    Download and unzip the Compatible SOPHONSDK from the official website of Sophgo,directory sophon-img_{date}_{time} includes libsophon_soc_x.y.z_aarch64.tar.gz, where x.y.z indicates the version number.

    # Create the root directory of the dependency files
mkdir -p soc-sdk
# Unzip libsophon_soc_x.y.z_aarch64.tar.gz
tar -zxf libsophon_soc_${x.y.z}_aarch64.tar.gz
# Copy the relevant library and header directories to the root of the dependency file
cp -rf libsophon_soc_${x.y.z}_aarch64/opt/sophon/libsophon-${x.y.z}/lib ${soc-sdk}
cp -rf libsophon_soc_${x.y.z}_aarch64/opt/sophon/libsophon-${x.y.z}/include ${soc-sdk}

  3. Package sophon-ffmpeg and sophon-opencv

    Download and unzip the Compatible SOPHONSDK from the official website of Sophgo, directory sophon-mw_{date}_{time} includes sophon-mw-soc_x.y.z_aarch64.tar.gz, where x.y.z indicates the version number. If you are using BM1688 SOPHONSDK, the prefix "sophon-mw" may be changed to "sophon-media".

    # unzip sophon-mw-soc_x.y.z_aarch64.tar.gz
tar -zxf sophon-mw-soc_${x.y.z}_aarch64.tar.gz
# Copy the ffmpeg and opencv library directory and header directory to the soc-sdk directory
cp -rf sophon-mw-soc_${x.y.z}_aarch64/opt/sophon/sophon-ffmpeg_${x.y.z}/lib ${soc-sdk}
cp -rf sophon-mw-soc_${x.y.z}_aarch64/opt/sophon/sophon-ffmpeg_${x.y.z}/include ${soc-sdk}
cp -rf sophon-mw-soc_${x.y.z}_aarch64/opt/sophon/sophon-opencv_${x.y.z}/lib ${soc-sdk}
cp -rf sophon-mw-soc_${x.y.z}_aarch64/opt/sophon/sophon-opencv_${x.y.z}/include ${soc-sdk}

  4. If you are using BM1688 & CV186AH SOPHONSDK, which's version >= 1.3, you will need to： get sophon-img/bsp-debs/sophon-soc-libisp_${x.y.z}_arm64.deb from GemeniSDK, then:

    dpkg -x sophon-soc-libisp_${x.y.z}_arm64.deb sophon-libisp
cp -rf sophon-libisp/opt/sophon/sophon-soc-libisp_${x.y.z}/lib ${soc-sdk}

Here, the cross-compilation environment has been built, and then you can use the packaged soc-sdk to compile the programs that need to run on the SoC platform. For more information on cross-compilation, please refer to the "LIBSOPHON Manual".

4.2 Cross-compiling and sophon-sail Installation

If the demo depends on sophon-sail, you need to compile and install sophon-sail, otherwise you can skip this section. You need to download the Compatible package of SOPHONSDK from the official website of Sophgo, enter sophon-sail_{date}_{time} directory, the sophon-sail source package is named in the format sophon-sail_x.y.z.tar.gz, where x.y.z indicates the version number. You can open the user manual provided in the same directory (named sophon-sail_en.pdf or SOPHON-SAIL_en.pdf). Refer to the compilation and installation guide chapter, and select the mode you need (C++/Python, SoC MODE) for installation. Note that you need to select Contains the compilation methods of ffmpeg and opencv. After you have followed the tutorial and copied the library files of Sophon Sail to the target SoC, you also need to set the following environment variables:

echo 'export LD_LIBRARY_PATH=/opt/sophon/sophon-sail/lib/:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc

5 arm PCIe Platform Development and Runtime Environment Construction

If you have installed PCIe accelerator card in arm platform, the development environment and running environment can be unified, you can directly build the development and running environment on the host. Here we provide the environment installation method for NeoKylin v10 machine, other types of machines please refer to the official development manual for details.

5.1 Installation of libsophon

Download the Compatible SOPHONSDK from the official website of Sophgo, libsophon installation package is under the directory libsophon_{date}_{time}, the installation package consists of a file where "$arch" is the hardware architecture of the current machine, and the current server's arch can be obtained using the following command.

uname -m

Usually the corresponding hardware architecture is x86_64 for x86_64 machines and aarch64 for arm64 machines:

libsophon_x.y.z_$arch.tar.gz, x.y.z indicates the version number.

It can be installed by following the steps below:

Note: If you have an old version, first refer to the uninstall steps below to uninstall the old version

tar -xzvf libsophon_${x.y.z}_aarch64.tar.gz
sudo cp -r libsophon_${x.y.z}_aarch64/* /
sudo ln -s /opt/sophon/libsophon-${x.y.z} /opt/sophon/libsophon-current

Next, set up your driver compilation environment according to the requirements of your Linux distribution, and then do the following operation:

sudo ln -s /opt/sophon/driver-${x.y.z}/$bin /lib/firmware/bm1684x_firmware.bin
sudo ln -s /opt/sophon/driver-${x.y.z}/$bin /lib/firmware/bm1684_ddr_firmware.bin
sudo ln -s /opt/sophon/driver-${x.y.z}/$bin /lib/firmware/bm1684_tcm_firmware.bin
cd /opt/sophon/driver-${x.y.z}

Here "$bin" is the full name of the bin file with version number, for bm1684x boards, e.g. bm1684x.bin_v3.1.0-9734c1da-220802, for bm1684 boards, e.g. bm1684_ddr.bin_v3.1.1-63a8614d-220906 and bm1684_tcm.bin_v3.1.1-63a8614d-220906.

Then, you can compile the driver (no dependency on dkms here):.

sudo make SOC_MODE=0 PLATFORM=asic SYNC_API_INT_MODE=1 \
          TARGET_PROJECT=sg_pcie_device FW_SIMPLE=0 \
          PCIE_MODE_ENABLE_CPU=1
sudo cp ./bmsophon.ko /lib/modules/$(uname -r)/kernel/
sudo depmod
sudo modprobe bmsophon

Finally, there are some configuration works:

Add library and paths for executable files

sudo cp /opt/sophon/libsophon-current/data/libsophon.conf /etc/ld.so.conf.d/
sudo ldconfig
sudo cp /opt/sophon/libsophon-current/data/libsophon-bin-path.sh /etc/profile.d/

You can use a command such as bm-smi after execute the following command in the terminal, or log out and log in to the current user

source /etc/profile

Add the cmake config file：

sudo mkdir -p /usr/lib/cmake/libsophon
sudo cp /opt/sophon/libsophon-current/data/libsophon-config.cmake /usr/lib/cmake/libsophon/

For other platform machines, please refer to "LIBSOPHON Manual"

Here we provide the environment installation method for SG2042, other types of machines please refer to the official development manual for details.

6.1 Installation of libsophon

Download the Compatible SOPHONSDK from the official website of Sophgo, libsophon installation package is under the directory libsophon_{date}_{time}, the installation package consists of three files:

sophon-libsophon-dev-{x.y.z}.riscv64.rpm
sophon-libsophon-{x.y.z}.riscv64.rpm
sophon-driver-{x.y.z}.riscv64.rpm

Before installing, you should uninstall old version libsophon refer to "Uninstallation" part. Then install by these steps:

#Install dependencies, only need to execute once.
sudo yum install -y epel-release
sudo yum install -y dkms
sudo yum install -y ncurses*
#Install libsophon：
sudo rpm -ivh sophon-driver-{x.y.z}.riscv64.rpm
sudo rpm -ivh sophon-libsophon-{x.y.z}.riscv64.rpm
sudo rpm -ivh --force sophon-libsophon-dev-{x.y.z}.riscv64.rpm
#Execute this command, or logout and login, then "bm-smi" is available.
source /etc/profile

Uninstallation:

sudo rpm -e sophon-driver
sudo rpm -e sophon-libsophon-dev
sudo rpm -e sophon-libsophon

For other platform machines, please refer to "LIBSOPHON Manual".

6.2 Installation of sophon-ffmpeg and sophon-opencv

Download the Compatible SOPHONSDK from the official website of Sophgo, sophon-mw installation package is under the directory sophon-mw_{date}_{time}, the installation package consists of four files:

sophon-mw-sophon-ffmpeg_{x.y.z}_riscv64.rpm
sophon-mw-sophon-ffmpeg-dev_{x.y.z}_riscv64.rpm
sophon-mw-sophon-opencv_{x.y.z}_riscv64.rpm
sophon-mw-sophon-opencv-dev_{x.y.z}_riscv64.rpm

Of which:

  1. sophon-ffmpeg/sophon-opencv contains the ffmpeg/opencv runtime environment (libraries, tools, etc.); sophon-ffmpeg-dev/sophon-opencv-dev contains the development environment (headers, pkgconfig, cmake, etc.). If you’re just installing on a deployment environment, you don’t need to install sophon-ffmpeg-dev/sophon-opencv-dev
  2. sophon-mw-sophon-ffmpeg depends on the sophon-libsophon package, and sophon-mw-sophon-opencv depends on sophon-mw-sophon-ffmpeg, so libsophon must be installed first in the installation order, then sophon-mw-sophon-ffmpeg, Finally install sophon-mw-sophon-opencv.

Before installing, you should uninstall old version refer to "Uninstallation" part. Then install by these steps:

sudo rpm -ivh sophon-mw-sophon-ffmpeg_{x.y.z}_riscv64.rpm sophon-mw-sophon-ffmpeg-dev_{x.y.z}_riscv64.rpm
sudo rpm -ivh sophon-mw-sophon-opencv_{x.y.z}_riscv64.rpm sophon-mw-sophon-opencv-dev_{x.y.z}_riscv64.rpm
#Execute this command, or logout and login
source /etc/profile

Uninstallation:

sudo rpm -e sophon-mw-sophon-opencv-dev
sudo rpm -e sophon-mw-sophon-opencv
sudo rpm -e sophon-mw-sophon-ffmpeg-dev
sudo rpm -e sophon-mw-sophon-ffmpeg

For other platform machines, please refer to "MULTIMEDIA User Manual", "Multimedia Development Reference Manual".

6.3 Compilation and Installation of sophon-sail

If the demo depends on sophon-sail, you need to compile and install sophon-sail, otherwise you can skip this section. You need to download the Compatible SOPHONSDK from the official website of Sophgo, sophon-sail installation package is under the directory sophon-sail_{date}_{time}, the package is named in the format sophon-sail_x.y.z.tar.gz, where x.y.z indicates the version number. You can open the user manual provided in the sophon-sail compressed package (named sophon-sail_en.pdf), refer to the compilation and installation guide chapter, and select the mode you need (C++/Python, RISCV PCIE MODE) for installation.

6.4 Install build tools

If you are using fedora os, and there is no default build tools, you will probably failed when using pip install xxx to install thirdparty wheels. Because most thirdparty wheels need to recompile on riscv platform, you can use these commands to install build tools, avoid from pip install xxx failing.

sudo dnf install ninja-build

6.5 Notes

If you are running a demo requiring torch on the RISC-V platform, you need to compile and install version 2.4.0 of torch yourself. If the demo depends on torchaudio or torchvision, you also need to compile and install versions compatible with torch. Specifically, the required version of torchaudio is 2.4.0, and the required version of torchvision is 0.19.0.

Additionally, you can directly install these dependencies using the pre-built wheel files we provide, which can be downloaded via dfss:

pip3 install dfss --upgrade
python3 -m dfss --url=open@sophgo.com:/sophon-demo/RISCV_Packages/wheels.tar.gz
tar xvf wheels.tar.gz
#Install dependencies by the provided requirements.txt file, such as:
pip3 install -r requirements.txt --no-index --find-links=wheels/
