We're going to use the <a href="https://huggingface.co/datasets/wikitext" target="_blank"><code>wikitext (link)</a></code> dataset with the <code><a href="https://huggingface.co/distilbert-base-cased" target="_blank">distilbert-base-cased (link)</a></code> model checkpoint.

<br/><br/>

Start by loading the <code>wikitext-2-raw-v1</code> version of that dataset, and take the 11th example (index 10) of the <code>train</code> split.<br/>
We'll tokenize this using the appropriate tokenizer, and we'll mask the sixth token (index 5) the sequence.

<br/><br/>

When using the <code>distilbert-base-cased</code> checkpoint to unmask that (sixth token, index 5) token, what is the most probable predicted token (please provide the decoded token, and not the ID)?

1. Create a python environment[1] and install `scikit-learn` version `1.0` in that environment.
<br/>
2. Using that environment, create a `LogisticRegression` model[2] and fit it on the Iris dataset[3].
<br/>
3. Save the trained model using `pickle`[4] or `joblib`[5].
<br/>
4. Create a second environment, and install `scikit-learn` version `1.1` in it.
<br/>
5. Try loading the model you saved in step 3 in this second environment.

<br/>
<br/>
Question:
<br/>
Is there a warning or error you receive while trying to load the model? If yes, what exactly is it.
