when I just try import matplotlib, then it doesn’t show any error msg.

but when I try some modules or a library using matplotlib like seaborn, it shows error msg.

If I write the import code below,

from matplotlib import pyplot as plt

soon it shows the msg below.

from matplotlib import pyplot as plt

and after few minuates, there comes the following error msg.

I tried everthing.

I set

import matplotlib as mpl
cache_dir = mpl.get_cachedir()
import shutil
shutil.rmtree(cache_dir)

!pip uninstall seaborn matplotlib -y
!pip install seaborn matplotlib

I made a virtual environment and re-installed every packages needed at onces.

python -m venv myenv
myenvScriptsactivate
source myenv/bin/activate

pip install numpy pandas matplotlib torch pydicom

when I install them all, it shows everything has gone alright.
but it shows error msg when I import a module from matplotlib.

It all has started when I try to setting up my new environment in my new M3-max macbook pro.
I didn’t have any problems like this when I was using intel macbook air 2017.

now I can’t do anything local environment.
Can you help me solve this problem?
