+# Start Jupyter Notebook With Extra Packages
+
+I can start up a one-off [Jupyter notebook](https://jupyter.org/) with
+[`uv`](https://docs.astral.sh/uv/) with the following command:
+
+```bash
+❯ uv run --with jupyter jupyter lab 
+```
+
+The `--with` flag is a `uv run` feature for [requesting additional
+dependencies](https://docs.astral.sh/uv/concepts/projects/run/#requesting-additional-dependencies).
+In this case, it includes the `jupyter` package as a dependency which is
+necessary for the command to then run `jupyter lab`.
+
+As I started following along with [Andrej Karpathy's "Neural Networks: Zero to
+Hero" series](https://karpathy.ai/zero-to-hero.html), I quickly ran into an
+issue with missing other dependencies. In the opening video, Andrej is importing
+`numpy` and `matplotlib`. To ensure those packages are also available for import
+in this notebook, I need to `--with` them as well.
+
+```bash
+❯ uv run --with jupyter --with numpy --with matplotlib jupyter lab 
+```
+
+Now, when I execute the following step, I don't have any import issues:
+
+```python
+import math
+import numpy as np
+import matplotlib.pyplot as plt
+%matplotlib inline
+```
