Pip reinstalling wx after wheel installation - Ubuntu 18.04 Python 3.8

bcimini · September 11, 2020, 3:47pm

Hi,

I work on an open source project (CellProfiler) that utilizes wx4.1.0 on Python 3.8- as part of our installation instructions for Ubuntu 16.04, 18.04, and 20.04(can’t link due to new user-2 link max, but it’s the same as the other ones and can be found in our wiki sidebar), we advise users to go grab the pre-compiled wx wheel, pip install it, then pip install our software.

On Ubuntu 16 and 20 this seems to work great, but on Ubuntu 18 on now a couple separate machines, we’ve seen that pip ignores the compiled wheel and builds itself from scratch again instead, which takes a few hours.

Is this a known issue? Is there something else we should be advising our users to do? Ultimately it’s not the end of the world, but certainly if they can avoid a long install that’s best.

Is it possible that those machines where it failed have an architecture other than x86_64? (Try “uname -m” if unsure.)

bcimini · September 11, 2020, 5:20pm

I wish that were the case, and I’d just made a silly error, but sadly seems not to be the case- I’m currently using the public AWS ami “Canonical, Ubuntu, 18.04 LTS, amd64 bionic image build on 2020-09-03” (ami-06b263d6ceff0b3dd) - I don’t know specifics for the other user, other than 18.04.

uname -m

x86_64

Okay, I’ve got a couple more shots in the dark for you:

Does it make any difference if you have pip do the downloading? Like this:

python3.8 -m  pip install -U \
  -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-18.04  \
  wxPython==4.1.0

Does it make any difference if you do the install inside of a venv?

python3.8 -m venv test38
source test38/bin/activate
pip install ...

Finally, if you add the -v flag to the pip install ... command it will show you lots of noise about all the links it finds and why each one is rejected. Digging through that might help shed some light on what is causing it to give up on the wheel file.

TL;dr, I think somehow the wheel is just not caching itself the way it’s supposed to outside of the venv; inside the venv, it works fine

Nope, same issue.

Result of installing python3.8 -m pip install -v -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-18.04 wxPython==4.1.0 below - I’ve cleaned out a lot of the “skipping link” lines. It claims to install fine.
