torch version issue: cannot import name 'download_url_to_file' from 'torch.hub'

[BrainNim]

Hello

When I run this code,

python mmskl.py pose_demo [--gpus $GPUS]

I met this error

Traceback (most recent call last):
  File "mmskl.py", line 7, in <module>
    import mmskeleton
  File "/content/mmskeleton/mmskeleton/__init__.py", line 1, in <module>
    from . import utils

    from .checkpoint import load_checkpoint, get_mmskeleton_url, cache_checkpoint

    from torch.hub import HASH_REGEX, _get_torch_home, download_url_to_file
ImportError: cannot import name 'download_url_to_file' from 'torch.hub' (/usr/local/lib/python3.7/site-packages/torch/hub.py)

So I search for the solution, but anything I can search is only 'torch version up'. (link1, link2)

I installed the version

# CUDA 9.2
conda install pytorch==1.2.0 torchvision==0.4.0 cudatoolkit=9.2 -c pytorch

following Getting_started.md.

If Getting_started.md was wrong, What torch, torchvision version should be installed?

thanks for your help

@BrainNim did you figure it out?

unfortunately not

I've checked pytorch package in local/official package and figured out that this function download_url_to_file exists. This issue was fixed by modifying mmcv. Just add undersore symbol at the begging of function call in "/usr/local/lib/python3.7/site-packages/mmcv-1.5.3-py3.7.egg/mmcv/utils/hub.py": download_url_to_file -> _download_url_to_file

@fronos Thanks a lot!!
