mmcv version

i am using google colab
pytorch =1.2.0
cuda=9.2

i have faced error like
Traceback (most recent call last):
File "/content/drive/My Drive/Colab Notebooks/GAN2Shape-main/run.py", line 7, in

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

so kindly suggest any way to proceed,
thank you.

me too.
pytorch 1.2 do not have public method download_url_to_file in package torch.hub

I resolved this by replacing line 20 in ~/anaconda3/envs/gan2shape/lib/python3.6/site-packages/mmcv/utils/hub.py to

from torch.hub import HASH_REGEX, _get_torch_home, _download_url_to_file

Then I needed to install a few more missing packages, ipython and tqdm
Also there was a missing library file, libcblas.so.3, needed by scipy , requiring libatlas-base-dev. Hope this helps.
