Run a Python code in MATLAB 2022b

I want ot run a Python code given here : Code Library Link in MATLAB 2022b.

I have installed Pyton 3.8 and installed this library also. I wrote this code

py = py.importlib.import_module('upsetplot');
plot_handel = py.UpSet;
generate_counts=py.generate_samples;
example_counts = generate_counts()
ax_dict = plot_handel(example_counts).plot()

I am getting this error.

example_counts =

I tested the code given on the link in Python and it worked. However its not woring in MATLAB. How can I resolve it?

The website says that output example_counts is a pandas.Series with 3-level Multi-index. Does MATALB is changing this thats why its not able to plot?

Thank You.

Hello @Masood Salik

The "IndexError" you are facing while using the 'plot' function of the "upsetplot.UpSet" Python library is likely related to the Tcl/Tk library, which is often used by the 'matplotlib' library for rendering plots when using the TkAgg backend. This issue typically arises when the Python environment is unable to locate the Tcl/Tk installation required for the TkAgg backend.

To resolve this, try specifying the TCL_LIBRARY and TK_LIBRARY environment variables to point to the correct directories in the MATLAB Command Window.

For example, you can use the code given below:

setenv('TCL_LIBRARY', 'C:\Users\USERNAME\AppData\Local\Programs\Python\Python38\tcl\tcl8.6');
setenv('TK_LIBRARY', 'C:\Users\USERNAME\AppData\Local\Programs\Python\Python38\tcl\tk8.6');

Using MATLAB 2022b and Python 3.8, I attempted to replicate the error you encountered. By setting the specified environment variables, I successfully resolved the issue and generated the desired plot. Please find the attached screenshot of the output for your reference.
