Impossible to build with matplotlib 3.3 on Python 3.7 and 3.8 #5004

Description of the issue

Trying a simple program main.py

import matplotlib.pyplot as plt

plt.plot([0,1,2], [0,1,1])

Running the application created with pyinstaller --hiddenimport='pkg_resources.py2_warn' main.py

I get:

What solves it

Reverting to matplotlib 3.2.2 resolve the issue (temporarily).

The text was updated successfully, but these errors were encountered:

rokm · 2020-07-18T10:12:44Z

Also happens on Fedora 32 with matplotlib 3.3:

As per the initial warning (MatplotlibDeprecationWarning: Matplotlib installs where the data is not in the mpl-data subdirectory of the package are deprecated since 3.2 and support for them will be removed two minor releases later.), matplotlib 3.3.0 requires the mpl-data directory to be in dist/matplotlib/ instead of dist/ itself.

The issue can be temporarily fixed by manually moving the mpl-data directory into matplotlib directory.

bwoodsend · 2020-07-18T12:14:10Z

Well for starters: matplotlib.plot doesn't exist. Use the following as a minimal example.

import matplotlib.pyplot as plt

plt.plot([0,1,2], [0,1,1])
plt.show()

But yes, it looks like @rokm is right. It's the data folder and that deprecation warning we've been putting off fixing has finally bit us. In which case the hook needs updating. I'll work on this.

bjonnh · 2020-07-18T18:58:08Z

Yeah sorry I wrote it from memory but I used pyplot.plt of course.

I ended up being able to make all of it work by reverting to a older matplotlib… I'll keep that for now as it reduces the amount of manual steps for distributing. And I'll update once the new hook is out.

Thanks for taking the time to work on the hook!

This alters where matplotlib's ``mpl-data`` folder is put and how it is found at runtime. This is to support matplotlib>=3.3.0 without breaking older versions. Fixes pyinstaller#5004. Previously, the data folder was places in the app's root and a runtime hook injected the environment variable ``MATPLOTLIBDATA`` to point to said folder. This variable was deprecated in ``matplotlib 3.1.0`` and now raises an error in ``matplotlib 3.3.0``. With this commit, hook-matplotlib.py puts the ``mpl-data`` folder where matplotlib is now (almost) hard-coded to expect it to be; which is in the parent folder of wherever ``matplotlib.__file__`` points to. With this move, we no longer need a runtime hook. When I say `almost hard-coded` above, I mean it appears like matplotlib meant to make it flexible but have mangled it as it now raises a ``NameError`` (see issue pyinstaller#5004) which presumably isn't intentional.

for me the solution presented here works
:
https://stackoverflow.com/questions/41870727/pyinstaller-adding-data-files

add the path to the matplotlib and matplotlib-base to the data section in the spec file . This seems to have fixed the issue. for now.Although i still get the deprecation warnings.

bwoodsend · 2020-11-02T20:27:23Z

@VenkatKaranam We've fixed this now. You should be able to just:

pip install -U https://github.com/pyinstaller/pyinstaller/archive/develop.zip

Then rebuild using the --clean option.

I have detected an error when you install Pathlib.

If you have Pathlib installed the error reported in this post starts to happen with every version of Matplotlib I have tried
When you uninstall Pathlib, the error stops to happen.

I don´t know how to fix it, but It seems fair to report here

Regards

bwoodsend · 2021-05-13T14:10:37Z

pathlib is standard library so you should never need to install it. Unfortunately, there is another pathlib on PyPI which, if installed, gets used instead and consequently breaks anything that wanted to use the original stdlib version. There's another package called enum with exactly the same problem.

@bwoodsend, hi i am relatively new to coding. how would i implement the "--clean option" you mentioned?

bwoodsend · 2021-11-23T19:10:09Z

pyinstaller --clean your-code.py but, given how old this is, I seriously doubt that whatever your problem is has anything to do with this.
