Parameters

• labels: single label or list-like Index or column labels to drop.

• axis: {0 or ‘index’, 1 or ‘columns’}, default 0 Whether to drop labels from the index (0 or ‘index’) or columns (1 or ‘columns’).

• index: single label or list-like Alternative to specifying axis (labels, axis=0 is equivalent to index=labels).

• columns: single label or list-like Alternative to specifying axis (labels, axis=1 is equivalent to columns=labels).

• level: int or level name, optional For MultiIndex, level from which the labels will be removed.

• inplace: bool, default False If False, return a copy. Otherwise, do operation inplace and return None.

• errors: {‘ignore’, ‘raise’}, default ‘raise’ If ‘ignore’, suppress error and only existing labels are dropped.

Moving forward, only labels (the first parameter) can be positional.

So, for this example, the drop code should be as follows:

Right now there is a PR to fix it but its not a released version. For now, just stick with

Alternatively, you can just wait for the visions package to be updated.

pip install thefuzz[speedup]

• The default pkgs/main channel for conda has reverted to using freetype 2.10.4 for Windows, per main / packages / freetype.
• If you are still experiencing the issue, use conda list freetype to check the version: freetype != 2.11.0
  • If it is 2.11.0, then change the version per the solution, or conda update --all (providing your default channel isn't changed in the .condarc config file).

• If this is occurring after installing Anaconda, updating conda or freetype since Oct 27, 2021.
• Go to the Anaconda prompt and downgrade freetype 2.11.0 in any affected environment.
  • conda install freetype=2.10.4
• Relevant to any package using matplotlib and any IDE
  • For example, pandas.DataFrame.plot and seaborn
  • Jupyter, Spyder, VSCode, PyCharm, command line.

• An issue occurs after updating with the most current updates from conda, released Friday, Oct 29.
• After updating with conda update --all, there's an issue with anything related to matplotlib in any IDE (not just Jupyter).
  • I tested this in JupyterLab, PyCharm, and python from the command prompt.
  • PyCharm: Process finished with exit code -1073741819
  • JupyterLab: kernel just restarts and there are no associated errors or Traceback
  • command prompt: a blank interactive matplotlib window will appear briefly, and then a new command line appears.
• The issue seems to be with conda update --all in (base), then any plot API that uses matplotlib (e.g. seaborn and pandas.DataFrame.plot) kills the kernel in any environment.
• I had to reinstall Anaconda, but do not do an update of (base), then my other environments worked.
• I have not figured out what specifically is causing the issue.
• I tested the issue with python 3.8.12 and python 3.9.7
• Current Testing:
  • Following is the conda revision log.
  • Prior to conda update --all this environment was working, but after the updates, plotting with matplotlib crashes the python kernel
