Issue with dependency Plotly

[rzelle-lallemand]

Just in case anybody else runs into this, there appears to be a problem with version 5.13.1 of the Plotly dependency (which as of this writing is the latest version). I updated Nanoplot to version 1.41.0 via conda earlier this week (conda update nanoplot), and got this error when attempting a run:

$ NanoPlot --fastq ... -o ...
Traceback (most recent call last):

ModuleNotFoundError: No module named 'packaging'

See also https://github.com/plotly/plotly.py/issues/4119 ("Plotly 5.13.1 introduces undeclared dependency to 'packaging'"). In my case I rolled back my conda environment to an earlier revision, although I guess people could also just install/update nanoplot normally as long as they specify a non-problematic version of plotly (e.g. conda install nanoplot plotly=5.13.0). This issue should mostly resolve itself once a new version of plotly is released.

Fixed in Plotly v5.14.0 onward (see release notes https://github.com/plotly/plotly.py/releases/tag/v5.14.0 ).
