Time Series / test_notebook[exploratory_data_analysis.ipynb]: ValueError: You must pass a freq argument as current index has none.

Problem

CI started tripping last week on the "Time Series" job, more specifically when validating the exploratory_data_analysis.ipynb notebook, which uses PyCaret.

ValueError: You must pass a freq argument as current index has none.

Proposal

• Either fix the regression, or Migrate from PyCaret to AutoGluon crate-clients-tools#207.

[amotl]

Those PyCaret tickets include the error message, maybe there is something inside that could help.

• [BUG]: You must pass a freq argument as current index has none pycaret/pycaret#2770
• time series numeric_imputation_target="ffill" is not working. and plot_model is not showing any visualization even after training pycaret/pycaret#3208

[amotl]

It was just about upgrading to ctk 0.0.30, which now uses the new datasets location at https://cdn.crate.io/downloads/datasets/cratedb-datasets/.

Fixed per:

• Time Series: Update Datasets API (ctk 0.0.30), because location changed #803
