I am so frustrated with pytorch. This is my 3rd time trying to install pytorch and try to learn it. It still failed to import torch.
I am using anaconda so I installed pytorch using
https://anaconda.org/pytorch/pytorch
conda install -c pytorch pytorch
(forecast) C:\Users\test>conda install -c pytorch pytorch

then I got below error, I did try to google it and I didn't find solution which works for me. why pytorch is so difficult to use? anyone can help me? Thanks
import torch

You can try to install using pip and you can find the prompt on the torch offfical website. Choose your cuda_version and use pip like this pip3 install torch torchvision torchaudio
This should work.
