Unable to import torchvision --AttributeError: module 'torch.jit' has no attribute 'unused'. Windows10, Python 3.7

Question

I am trying to import torchvision but I am getting an error. I researched the topic in the Web and there seems to be a problem with the later versions. Different solutions were offered --mostly reinstalling the modules-- which I tried without a result The latest advice I found was to install torch and torchvision using the following command which I did successfully:

pip install torch===1.4.0 torchvision===0.5.0 -f https://download.pytorch.org/whl/torch_stable.html

Still, the error persists:

I am running Windows10, Anaconda 3, Python 3.7. My PC has a GPU and I have installed CUDA which works with TensorFlow and PyTorch.

Answer 1

For me downgrading torchvision to 0.4.0 did the trick:

pip uninstall torchvision
pip install torchvision==0.4.0 -f https://download.pytorch.org/whl/torch_stable.html

Answer 2

I was able to import torchvision in an Environment ruining Python 3.6. It was impossible to run it with Python 3.7.

Answer 3

I am able to get this to run with the following commands:

conda create --name test5 python=3.6
conda install -c pytorch pytorch torchvision cpuonly

python
>>> import torch
>>> import torchvision

Answer 4

tl;dr pip3 install torchvision to upgrade torch and torchvision to latest compatible versions.

torchvision 0.7 has been released and is compatible with torch 1.6. It does not appear to be compatible with torch 1.5.

Note that installing torchvision via PyCharm may not result in an automatic upgrade of torch. Installing via pip3 did automatically upgrade torch however.
