TypeError: '<=' not supported between instances of 'str' and 'int' when using fit_predict

I am trying to utilize silhouette analysis on KMeans clustering in order to determine how to choose the optimal number of clusters in a given dataset.
I tried the example code provided on [scikit-learn](https://scikit-learn.org/stable/auto_examples/cluster/plot_kmeans_silhouette_analysis.html#) but it seems to produce an error whenever I try to run it.

Traceback:
```

Is there something I am missing here? I iterated through the sample data and did not see any strings present in `X`. I copied and ran the exact same code as present on the website.

Thank you!

COMMENT:
The examples on the stable webpage `https://scikit-learn.org/stable/` is validate for scikit-learn version 1.2. From the error message, I suspect you are on an older version of scikit-learn. Can you check your scikit-learn version to confirm?

For old versions such as 1.1, you can look at the same example but change the version in the URL: https://scikit-learn.org/1.1/auto_examples/cluster/plot_kmeans_silhouette_analysis.html# (Note the "1.1" in the URL)
