gadgetCPU.gadgetInit() report an error!

[xscjun]

When I run the code:
gadgetCPU = SpeedTorch.DataGadget( 'data.npy',CPUPinn=True)
gadgetCPU.gadgetInit()

report an error like this:
Exception ignored in: <function PMemory.del at 0x7fcef8ca86a8>
Traceback (most recent call last):
File "/usr/local/python3/lib/python3.7/site-packages/SpeedTorch/CUPYLive.py", line 19, in del
AttributeError: 'NoneType' object has no attribute 'runtime'

But it's ok when I run :
gadgetGPU = SpeedTorch.DataGadget( 'data.npy' )
gadgetGPU.gadgetInit()

I can't find the reason,it confused me .

Hi xscjun,

That is very confusing. I am investigating by trying to recreate the issue. So far I am unable to re-create the issue in Colab.

Here's the code I used

!pip install SpeedTorch
#Always import cupy before SpeedTorch 
import cupy
import SpeedTorch
import torch
import numpy as np
import torch.nn as nn

sampl = np.random.uniform(low=-1.0, high=1.0, size=(10, 10, 10, 10))
np.save('data.npy', sampl)
del sampl

gadgetGPU = SpeedTorch.DataGadget( 'data.npy', CPUPinn=True )
gadgetGPU.gadgetInit()

For convenience, here's the colab notebook I used.

Are you able to recreate the issue in Colab? If so, link a notebook for further investigation.

If not, it looks like it's an issue with your system. In that case, you could provide your system information and see if we can figure out what is causing the error from that info.

Thanks for your reply，It's the python3.7 that report the error, I change the version of python to 2.7, It's ok now.

[Santosh-Gupta]

Glad you were able to get it working. I am wondering what the cause is; I did all my testing in Python 3.

I can't get it working in python3.7 ,it is confusing.

[Santosh-Gupta]

I noticed Colab has Python 3.6.8 by default, so perhaps there is something off about 3.7.

Are you able to recreate the issue in Colab? Is the 'data.npy' the same as in the notebook?

The 'data.npy' is the same as in the notebook. I haven't recreate the issue in Colab

I got OOM error, how can I deel with it? BTY, how can I load multiple data in one container？

Can you make a colab that reproduces this error? That way I can interact with the bug.

BTY, how can I load multiple data in one container？

I haven't put that feature in, but I can put it in. So you would want
ModelFactoryObject.loadCupy( loadFileName) for the first dataset, and then
for new datasets. something like
ModelFactoryObject.appendCupy( loadFileName2)

?

import cupy
import SpeedTorch
gadgetGPU = SpeedTorch.DataGadget('mel-20170001P00084I0004.npy')
gadgetGPU.gadgetInit()
mel-20170001P00084I0004.zip
It seems gadgetGPU.gadgetInit()will result this error no matter which data I load.

[Santosh-Gupta]

It looks like the data format is incorrect. It looks like there's an issue with how you're saving the data, and/or how your zipping the file.

Checkout this notebook, which saves and loads numpy data

https://colab.research.google.com/drive/185Z5Gi62AZxh-EeMfrTtjqxEifHOBXxF

Try using numpy.save to directly save your data into a numpy format file.

It seems hard to change the data formate as my model has trained for a long time... Is there any method I can transfer data from CPU to your container? Or is there any method can replace torch.utils.data.Dataloader in pytorch? For example I've already preprocessed my data and saved it in a list.

[Santosh-Gupta]

Yup, I forgot the exact commands, but you can access your embedding data and mount them to CPU, in numpy form. It looks something like this YourModel.YourEmbeddingVariable.Weight.data.cpu().numpy()

Can't open the link... I don't mean the embedding data like weight or parameters in model, I mean the training data, a set of data loaded in CPU, the time cost usually waste on loading batch from CPU to GPU. So I was wondering if I could save training data in speedtorch. It will helpful if there is a document to explain those functions in speedtorch.

[Approximetal]

Thank you for replying! I can load files by using speedtorch now. But cupy doesn't support multi-thread, so I have to modify the thread from 8 to 1, after that, the time cost is even longer......

[Santosh-Gupta]

Yes, as long as the data is saved in numpy format, data gadget can open it, or your could transfer live data onto there. If you give me a colab notebook which loads your data, I can tinker around with it. I think the easiest way to do this to upload your data onto google drive, then use !gdown --id followed by the google drive id to download it directly to your notebook.

There's documentation at the bottom of the readme, and here's a colab notebook which shows how to use the data gadget:
