Avec Python 3.12.3 :

Python 3.12.3 (main, Feb  4 2025, 14:48:35) [GCC 13.3.0]
Version: v1.10.1
Commit hash: 82a973c04367123ae98bd9abdf80d9eda9b910e2
Installing torch and torchvision
Looking in indexes: https://pypi.org/simple, https://download.pytorch.org/whl/cu121
ERROR: Could not find a version that satisfies the requirement torch==2.1.2 
(from versions: 2.2.0, 2.2.0+cu121, 2.2.1, 2.2.1+cu121, 2.2.2, 2.2.2+cu121, 
2.3.0, 2.3.0+cu121, 2.3.1, 2.3.1+cu121, 2.4.0, 2.4.0+cu121, 2.4.1, 
2.4.1+cu121, 2.5.0, 2.5.0+cu121, 2.5.1, 2.5.1+cu121, 2.6.0, 2.7.0)
ERROR: No matching distribution found for torch==2.1.2

Donc j’utilise Python 3.11 :

# apt-get install python3-setuptools
# apt-get install python3-build
# python3.11 -m pip install --upgrade pip setuptools wheel
# virtualenv -p /usr/bin/python3.11 venv
created virtual environment CPython3.11.12.final.0-64 in 1366ms
  creator CPython3Posix(dest=/home/XXXX/stable-diffusion-webui/venv, clear=False, 
no_vcs_ignore=False, global=False)
  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, 
via=copy, app_data_dir=/home/XXXX/.local/share/virtualenv)
    added seed packages: pip==24.0, setuptools==68.1.2, wheel==0.42.0

$ source venv/bin/activate
$ python3.11 -m pip install --upgrade pip setuptools wheel
$ bash webui.sh --api --listen

Python : test de la librairie calplot

En passant

Le plus longs c’est de fixer les problèmes Python …

findfont: Font family 'Helvetica' not found.

Ensuite quelques lignes de code :

import pandas as pd
import calplot
import pylab
from matplotlib import rcParams

df_tem = pd.read_csv('./VeloResume2020-2024-v4.csv', delimiter=";")
df_tem2 = df_tem.groupby([df_tem['date'].dt.date,'activity'])['km'].sum().reset_index().rename(columns={'sum':'km'})
df_tem2 = df_tem2.query('activity=="E-Biking"'
fig = calplot.calplot(df_tem2['km'],
                cmap="BuGn",
                fillcolor="w",
                linecolor="w",
                suptitle_kws=csfont,
                yearlabel_kws={'fontname':'sans-serif'},
                fig_kws=dict(facecolor="w"),
                subplot_kws=dict(facecolor="w"),
                edgecolor="grey")
pylab.savefig('E-Biking.png')

Python : matplotlib : Issue line 303 text.parse_math

Sur Kali OS j’ai eu cette erreur :


Bad key text.parse_math in file /usr/share/matplotlib/mpl-data/matplotlibrc, line 303 ('text.parse_math: False # Use mathtext if there is an even number of unescaped')
You probably need to get an updated matplotlibrc file from
https://github.com/matplotlib/matplotlib/blob/v3.5.2/matplotlibrc.template
or from the matplotlib source distribution

raise ValueError(f"Key {key}: {ve}") from None
ValueError: Key grid.color: '"' does not look like a color arg

J’ai donc edité le fichier /usr/share/matplotlib/mpl-data/matplotlibrc pour mettre en commentaire la ligne ( sachant que False ou True on a la même erreur) :


##text.parse_math: True

Mais je suis pas sûr que cela fixe le problème … cela plante un peu plus loin.
