I started learning matplotlib with the Python Data Science Handbook by Jake VanderPlas that starts with this code for importing and setting style:
%matplotlib inline
import matplotlib.pyplot as plt
plt.style.use('seaborn-whitegrid')
import numpy as np
First, I got this error:
'seaborn-whitegrid' is not a valid package style, path of style file, URL of style file, or library style name (library styles are listed in style.available)
I tried:
print(plt.style.available)
But the 'seaborn-whitegrid' was not listed. Then I went for updating packages:
pip install --upgrade matplotlib seaborn
Still it did not work. Now I get this error:

Is this way of setting the style not valid anymore? Do I have to use:
import seaborn as sns
sns.set(style='whitegrid')
What else can I do?
After trying the recommended uninstall and reinstall, I got another error telling me it cannot uninstall:

But trying the offered command returns the same result!
I still do not know what to do with this. So I start with this import now:
%matplotlib inline
import matplotlib.pyplot as plt
import seaborn as sns
sns.set_style("whitegrid")
Again, it results in this long traceback:

Then, by calling plt like this, I get this other traceback telling me plt is not defined:
fig = plt.figure()
ax = plt.axes()
Obviously, the previous error didn't let it to be imported correctly, as the error implies:
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
Cell In[2], line 1
----> 1 fig = plt.figure()
2 ax = plt.axes()
NameError: name 'plt' is not defined
The last thing I did was manually deleting all the residual files and remnanats from the previous installations. All the files named matplotlib, mpl_toolkits, ~atplotlib, or similar in the C:\Users\asus\AppData\Local\Programs\Python\Python313\Lib\site-packages folder had to go to restart with a clean slate. Then reinstall packages with:
pip install --upgrade ipython jupyter matplotlib
Now these work seamlessly:
%matplotlib inline
import matplotlib.pyplot as plt
import seaborn as sns
sns.set_style("whitegrid")
import numpy as np
fig = plt.figure()
ax = plt.axes()
