Some notebooks that misuse matplotlib GridSpec started failing to run, due to this commit in matplotlib: matplotlib/matplotlib@308ce5d49f455c9698de75f7e93d12c8a312f2e0
Basically height_ratios and width_ratios now raise a ValueError if their length doesn't match the specified number of rows/columns in the plot.
