Error on pytorch install

ERROR: torch-1.7.0+cpu-cp37-cp37m-win_amd64.whl is not a supported wheel on this platform.

Are you using a 32bit Python installation in your current environment? If so, you would need to install a 64bit package and retry the install steps.
If that’s not the case, could you give more information about your system and setup?

environment?

you can print your environment with:
wget https://raw.githubusercontent.com/pytorch/pytorch/master/torch/utils/collect_env.py

then,
python collect_env.py

my computer is 64-bit。

‘wget’ is not recognized as an internal or external command,
operable program or batch file.

and I install a 64-bit package

Your Python installation could be a 32bit version regardless which CPU/OS you are using.

ok, you are right. The problem is 32-bit python. I accidentally did that.
