YAML Parsing Error in Jupyter Lab

[gilbertmike]

To replicate, do the following inside Jupyter Lab:

• Parse YAML file into v4 specification.
• Call to_model_app.

These steps will lead to an error when Timeloop parses the configuration. Specifically, integer values (e.g., 1) will no longer be recognized as integers (although looking correct from manual inspection of the generated YAML string), leading to CompoundConfigNode.lookupValue to look for a variable (e.g., "1") under the variable key.
