[Solved] Protobuf problems

I installed protobuf-31.0-2 and when I install AUR python libraries, this happens:
ImportError: libprotobuf.so.30.2.0: cannot open shared object file: No such file or directory
Maybe protobuf is too new?

Re: [Solved] Protobuf problems

You probably need to rebuild those aur python librairies so they'll use the new protobuf .



Moderator Note: moving to aur board.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?

Re: [Solved] Protobuf problems

Look at the FULL error, not just the part you posted. See what it is that's trying to import the old lib.

So this is happening when importing torch. Sounds like a partial update, did you ignore updates to whatever torch package you're using?

And please, use code tags when pasting these things!
