I do not why this always happend.I have create two clean conda envs（python=3.7, and python=3.6），but the same wrong.

I'm facing the same issue while importing torchvision in python 3.6

EDIT: Somehow uninstalling torch and torchvision and deleting the copies from /lib/python3.6/site-packages/ and reinstalling them fixed my issue.
The current versions are as follows: torch-1.1.0 torchvision-0.3.0.

@adityakillekar your tips successfully solve my problem~~

[GinSoda]

I faced the same problem,
you can try pip install -U torchvision==0.4.0 .
That works for me.

[tall-josh]

Yep

pip remove torchvision
pip install torchvision==0.4.0

worked for me :-)

[Antoine-ls]

@GinSoda but this will change torch version to 1.2.0 right? will that work for this project?

[leo2105]

if you have build folder, create again using the current pytorch version

if you have build folder, create again using the current pytorch version

I don't understand the term "build folder" unfortunately. What folder are you referring to specifically?

Thank you! It works!

Solved it with installing cuda10.1 and running
pip install torch==1.6.0+cu101 torchvision==0.7.0+cu101 -f https://download.pytorch.org/whl/torch_stable.html

@rvorias did you use pip to install cuda10.1?? If so then can u please suggest me a link for the same. I went https://download.pytorch.org/whl/cu100/torch_stable.html for the wheel file but I couldn't find one for my specs. I use linux and torch==1.5.0+cu101 torchvision==0.6.0

[ramithuh]

Worked for me after upgrading as suggested (pytorch/audio#62 (comment)). Might be need to be careful with the version you intend to use though.

pip install -U torch torchvision --no-cache-dir
