[cloudQuant]

Description

I using mac 15.3.2 (24D81) and python 3.11

when I install the qlib using this code:
git clone https://github.com/microsoft/qlib.git && cd qlib pip install .
and download data using this code in the qlib:
python scripts/get_data.py qlib_data --target_dir ~/.qlib/qlib_data/cn_data --region cn
I get these errors:

@yuns-MacBook-Air-4 qlib % python scripts/get_data.py qlib_data --target_dir ~/.qlib/qlib_data/cn_data --region cn

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

Alternatively, set the version with the environment variable SETUPTOOLS_SCM_PRETEND_VERSION_FOR_${NORMALIZED_DIST_NAME} as described in https://setuptools-scm.readthedocs.io/en/latest/config/

Hi, @cloudQuant

The problem you are experiencing is due to the incomplete code you are pulling, it is recommended that you reinstall qlib using the following commands:

git clone https://github.com/microsoft/qlib.git 
cd qlib 
python -m pip install -e .

Once the reinstallation is complete, the problem should be resolved. There is no need to change the code.
