Thanks for your books.

> Describe the bug

I expected to find this issue, but didn't.

French version, 2d ed., chapitre 1, p. 4.

Using `python3 -m ipykernel install --user --name=python3`, as shown in the book, doesn't work. Remove the `=` sign solves it.

Thanks.

**To Reproduce**

```bash
python3 -m ipykernel install --user --name=python3
```

**Expected behavior**

Declare tf2 for Jupyter as python3

**Versions (please complete the following information):**
- MacOSX 10.15.7
- Python 3.8
