[Bug]: Issue installing python-torch

[dzuberi]

Problem description

I'm trying to install python-torch to use pytorch as a dependency for some other python modules. When I try installing it, the output looks something like this

$ pkg install python-torch

It appears to be running some post-installation script but trying to access the root directory. I haven't seen anyone else with this issue, but posting here in case I am first by some miracle, or if not to get some advice on getting past this issue

What steps will reproduce the bug?

pkg install python-torch

What is the expected behavior?

Maybe you can try to update apt or install dpkg again? I didn't encounter error installing python-torch

[licy183]

I can't reproduce this error too... Are are using pip distributed by Termux's apt?

Besides, starting from #19748 (python-torch 2.1.2-2 ), python-torch has been moved to the x11 repository. However, it seems that the package still exists in the main repository.

Ping @Grimler91 Could you please remove python-torch from the main repository?

[dzuberi]

@licy183 I'm using python-pip installed from pkg install python-pip, so I think so.

@Duuckjing I've run pkg update && pkg upgrade and apt update && apt upgrade (which I think do the same thing). How do I reinstall dpkg?

[dzuberi]

I tried pkg reinstall dpkg but the issue persists

[dzuberi]

So I also tried

pkg install x11-repo
pkg update && pkg upgrade
pkg install python-torch

after @licy183's comment but the same error occurs

edit: actually python-torch is still being sourced from the main repo in this instance

[dzuberi]

Update: I also tried manually downloading and installing the dpkg from the x11 repo and I get the same error

[licy183]

I still don't think that you're using the python-pip shipped by Termux. Try rm $PREFIX/lib/python3.11/site-packages/pip && apt install --reinstall python-pip.

[dzuberi]

@licy183 unfortunately that didn't help, sorry for the late response

[dzuberi]

I ended up just reinstalling termux, curious what went wrong but I decided to just start over
