Project scenario :
I did it again today anaconda, Put on miniconda(anaconda It's too big , Many useless bags occupy space , also pycharm Often index pkg The file of ).
Problem description 1
reinstall conda after , Then match Tsinghua source , Just want to put pytorch packed , according to pytorch Official website order , Copy and download , However, installation was not found torch The speed is still relatively slow .
conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
Cause analysis :
At the end of the command -c pytorch Need to get rid of it. , Otherwise, the command defaults to go pytorch Source , Still unable to use the speed of domestic sources .
Solution :
Just delete the ending .
conda install pytorch torchvision torchaudio cudatoolkit=11.3
Problem description 2
After configuration as required , Follow the command to download pytorch, Later, I encountered a problem ,PackagesNotFoundError: The following packages are not available from current channels:
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Cause analysis :
pytorh Some dependent packages are not available in the current channel .
Solution :
stay .condarc Modify the file , hold pytorch Raise the priority

Don't ctrl+c interrupt
In the installation to pytorch When this bag , And then install it to 99 When , It seems to have stopped and failed , It's not , After downloading the package , The compressed package must be decompressed , Then it has to be transmitted to the corresponding env Inside , So it takes more time , I looked as if it had failed twice before , Then interrupt , Lead to conda There is also a cache left , need conda clean --all Clean up and download again , Wasted a lot of time .
