[tigran123]

Problem description

Trying to install matplotlib package fails. First it fails with the missing spawn.h header error, but after installing the libandroid-spawn package it fails in a different way.

Post the whole log please.

Here is the full typescript of pkg install matplotlib

[romanovj]

pkg i ninja patchelf

[tigran123]

Thank you, that worked. But presumably those two packages should be listed as dependencies and installed automatically?

[tigran123]

And now pip install gmpy fails with longinterp.h header missing...

[romanovj]

And now pip install gmpy fails with longinterp.h header missing...

gmpy 1.17 - release Jul 28, 2013

you can try your luck with 2.1.5 or switch to older python

pip install https://github.com/aleaxit/gmpy/archive/refs/tags/gmpy2-2.1.5.tar.gz

My python programming environment has modules installed with pip in a virtual environment,
and I want to install matplotlib there as well. I was able to install it on Termux with pkg in the way described here,
but in the my activated virtual-env install matplotlib is failure
(env) [1.164s] [~/pyprog]$ pip install matplotlib
I can't install this with a wheel error If you have any ideas or suggestions, I would appreciate it

P.S. and information
Before coming here, I looked at the following topics and entered the command
https://github.com/termux/termux-app/discussions/3444
I don't understand what those commands mean :)
I'd like to post a log of the errors, but I'll upload the whole thing somewhere if necessary

(env) [1.164s][~/pyprog]$ pip install matplotlib Collecting matplotlib Using cached matplotlib-3.8.2.tar.gz (35.9 MB) Installing build dependencies ... error error: subprocess-exited-with-error × pip subprocess to install build dependencies did not run successfully. │ exit code: 1 ╰─> [92 lines of output] .
.


By installing the same necessary modules as in the virtual environment on the pip on the raw termux environment side, which is not currently a virtual environment,
It can be used as an environment with matplotlib this is good, but the problem is not solved it

[romanovj]

@Suletta-Majo you can copy required modules from /data/data/com.termux/files/usr/lib/python3.11/site-packages to lib/python3.11/site-packages inside your venv

[Suletta-Majo]

@romanovj There were two directories, so I moved them with cp matplotlib*
has appeared in pip list in env! :) In the Python program for the graph image output test
The matplotlib module import error is gone, but I get a new numpy error
errormsg.txt

my testing code mplottes.py

import matplotlib.pyplot as plt

plt.plot([1, 2, 3])
plt.savefig('myfig.png')

On the raw termux side that is not a virtual environment, the graph creation was successful, and I was able to view the image with Chafa
Both are the same numpy version
I wonder if there are still things that aren't installed as dependencies? ☹️

[romanovj]

@Suletta-Majo patchelf --add-needed libpython3.11.so /data/data/com.termux/files/home/pyprog/env/lib/python3.11/site-packages/numpy/core/_multiarray_umath.cpython-311.so

[Suletta-Majo]

@romanovj thanks I tried it, but there error seems to be no change errormsg2.txt

[romanovj]

@Suletta-Majo try to execute inside venv, it will install all missing deps pip install matplotlib

you can also replace folders with numpy module inside venv with standart termux module

[Suletta-Majo]

@romanovj on my virtual-environment pip install matplotlib is run completed! but error is same

Let's run python and modules in a virtual environment on the site I learned because it was recommended and so I just followed it. I would like to move to programming in a direct environment that is easy and simple in terms of Termux😓 I'm not advanced user and As it is happening now, it is not like I can Corrections and countermeasures with it. thanks

[romanovj]

@Suletta-Majo did you replace numpy in venv with numpy from /data/data/com.termux/files/usr/lib/python3.11/site-packages ?

[Suletta-Majo]

@romanovj Because the machine translation displayed the copy source and destination as if it were reversed.
I didn't do it because I didn't understand the purpose of this work, but I understood it with a new statement and carried
it out Errors are now concise and short, and I feel like they can be solved
somehow Is this a good way to uninstall some duplicate matplotlib? (env) [165ms][~/pyprog]$ python3 mplottes.py /data/data/com.termux/files/home/pyprog/env/lib/python3.11/site-packages/matplotlib/projections/init.py:63: UserWarning: Unable to import Axes3D. This may be due to multiple versions of Matplotlib being installed (e.g. as a system package and as a pip package). As a result, the 3D projection is not available. warnings.warn("Unable to import Axes3D. This may be due to multiple versions of "

additional info below. my termux installed 3way matplotlib :/ not checked pip3 list rawandenvpip.txt

[Suletta-Majo]

success! thankyou @romanovj

i not copyed all required module
so when copy start. i found mystery module named mpl_toolkit
i copy this to venv module directory then plotprogram completed run and generate png graph successfully!
