问题
Would appreciate an explanation like I'm 5 simply because I have checked all relevant answers and none have helped.
I have installed Python. I have installed Pycharm. I have installed Anaconda. I have installed Microsoft Visual Studio. I have not installed the CUDA toolkit.
In Anaconda, I used the commands mentioned on Pytorch.org (06/05/18)
conda install pytorch -c pytorch
pip3 install torchvision
Both have downloaded and installed properly, and I can find them in my Users/Anaconda3/pkgs folder, which I have added to the Python path.
Trying to enter
import torch
in the Python console proved unfruitful - always giving me the same error,
No module named 'torch'
I have also tried using the Project Interpreter to download the Pytorch package. It worked for numpy (sanity check, I suppose) but told me to go to Pytorch.org when I tried to install the "pytorch" or "torch" packages.
When trying to use the console in PyCharm, pip3 install codes (thinking maybe I need to save the packages into my current project, rather than in the Anaconda folder) return me an error message saying
torch-0.4.0-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform.
The same message shows no matter if I try downloading the CUDA version or not, or if I choose to use the 3.5 or 3.6 Python link (I have Python 3.7)
Currently the closest I have gotten to a solution, is manually copying the "torch" and "torch-0.4.0-py3.6.egg-info" folders into my current Project's lib folder. However, when I do that and then run "import torch" I received the following error:
Traceback (most recent call last):

回答1:
pip uninstall torch
then
pip install torch worked for me.
回答2:
I encountered the same problem because I updated my python from 3.5 to 3.6 yesterday. I think the connection between Pytorch and Python is not correctly changed. Thus, I installed Pytorch for 3.6 again and the problem is solved. Check the install command line here[1].
