I can not use the plots

[Roanol]

Describe the bug

when trying to plot it raises: TypeError("Instance and class checks can only be used with" TypeError: Instance and class checks can only be used with @runtime_checkable protocols

To Reproduce

any of the examples

from skfda import datasets from skfda.exploratory.depth import ModifiedBandDepth, IntegratedDepth from skfda.exploratory.visualization import Boxplot

import matplotlib.pyplot as plt import numpy as np

X, y = datasets.fetch_weather(return_X_y=True, as_frame=True) fd = X.iloc[:, 0].values fd_temperatures = fd.coordinates[0]

colormap = plt.cm.get_cmap('seismic') label_names = y.values.categories nlabels = len(label_names) label_colors = colormap(np.arange(nlabels) / (nlabels - 1))

fd_temperatures.plot(group=y.values.codes, group_colors=label_colors, group_names=label_names)

Expected behavior

Ploting something

As you can see its in any kind of plot

[vnmabus]

What is the version of the typing_extensions package?

[Roanol]

typing_extensions==4.6.2

[vnmabus]

I was able to reproduce it and I am trying to solve this. As a stopgap measure you can downgrade that package to version 4.3, which worked well.

[Roanol]

thanks!

[vnmabus]

I traced this to a bug in the module typing_extensions (https://github.com/python/typing_extensions/issues/207), which in turn was caused by copying buggy behavior from Python 3.11 (https://github.com/python/cpython/issues/105144).

The authors of typing_extensions have updated their package to version 4.6.3, which should solve this issue. Please, tell me if that works for you.

[gedeck]

I came across the same issue and can confirm that upgrading typing-extensions to the latest version solves issue.

[vnmabus]

I will close the issue then, since it seems to be solved.
