// An opintionated skill to prepare a marimo notebook to make it ready for a scheduled run.
Write a marimo notebook in a Python file in the right format.
Implement a research paper in a marimo notebook fully automatically without extra user input.
Make a demo of a research paper in a marimo notebook fully automatically without extra user input.
Implement a research paper as an interactive marimo notebook together with the user. Start by understanding what the user wants to explore, fetch the paper via alphaxiv, then build a focused notebook.
Generate anywidget components for marimo notebooks.
Convert a Jupyter notebook (.ipynb) to a marimo notebook (.py).

Pydantic is a great way to declare a source of truth for a batch job, especially for ML. You can declare something like:
from pydantic import BaseModel, Field
class ModelParams(BaseModel):
sample_size: int = Field(
default=1024 * 4, description="Number of training samples per epoch."
)
learning_rate: float = Field(default=0.01, description="Learning rate for the optimizer.")
You can fill these model params with two methods too, you can imagine a form in the UI.
el = mo.md("""
{sample_size}
{learning_rate}
""").batch(
sample_size=mo.ui.slider(1024, 1024 * 10, value=1024 * 4, step=1024, label="Sample size"),
learning_rate=mo.ui.slider(0.001, 0.1, value=0.01, step=0.001, label="Learning rate"),
).form()
el
But you can also use the CLI from marimo.
if mo.app_meta().mode == "script":
if "help" in mo.cli_args() or len(cli_args) == 0:
print("Usage: uv run git_archaeology.py --repo <url> [--samples <n>]")
print()
for name, field in ModelParams.model_fields.items():
default = f" (default: {field.default})" if field.default is not None else " (required)"
print(f" --{name:12s} {field.description}{default}")
exit()
model_params = ModelParams(
**{k.replace("-", "_"): v for k, v in mo.cli_args().items()
})
else:
model_params = ModelParams(**el.value)
The user can now run this from the command line via:
uv run notebook.py --sample-size 4096 --learning-rate 0.005
This is the best of both worlds, you can use the UI to test and iterate, and then use the CLI to run the batch job. Another benefit is that you can run the notebook with settings to make it run quickly to see if there are any bugs in the notebook.
The user wants to be able to run a notebook using this pattern, so make sure you ask the user which parameters they want to make configurable via the CLI and the proceed to make the changes to the notebook. Make sure you verify the changes with the user before making them.
It is possible that the user is interested in adding support for weights and biases. Make sure you confirm if this is the case yes/no. If that is the case, make sure these ModelParams are logged. You also want to make sure that the wandb_project and wandb_run_name are part of the ModelParams is the user wants to go down this route.
If the user is keen to start a training job for ML, make sure you use this starting point. Make sure you keep the columns intact in this notebook!
You may need to read environment variables for the job. Use python-dotenv to read a .env file if it exists, but also add an EnvConfig so users may add keys manually in a ui.
from wigglystuff import EnvConfig
# With validators
config = EnvConfig({
"OPENAI_API_KEY": lambda k: openai.Client(api_key=k).models.list(),
"WANDB_API_KEY": lambda k: wandb.login(key=k, verify=True)
})
# Block until valid, useful in cell that needs the key
config.require_valid()
# Access values
config["OPENAI_API_KEY"]
config.get("OPENAI_API_KEY", "some default")
Make sure you add this EnvConfig at the top of the notebook.
It can be common for larger marimo notebooks to use the columns feature to make it easy to navigate. If that is the case, you must keep these columns intact!
@app.cell(column=0, hide_code=True)
def _(mo):
mo.md(r"""demo""")
When the job is ready to get some serious compute, it is important that we keep good practices in mind. Consider batch sizes for the data set and make sure that there are plenty of logs so the user can spot if issues arise.
When the user wants to run a hyperparameter sweep, point them to this grid launcher. It works with the notebook in references/starting-point.py out of the box: it samples random combinations from a search space that matches the notebook's ModelParams fields and launches each one as a separate job.
By default the script does a dry run (uv run grid.py) so the user can inspect the combinations before spending compute. Pass --launch to actually submit jobs. The --count and --seed flags control how many combinations to sample and the RNG seed.
The reference uses Hugging Face Jobs as the compute provider, but this is just one option. The user can swap it out for Modal, RunPod, or any other provider that can run a uv script.
