'Figure' object has no attribute 'draw_without_rendering'

[AlcaArctica]

I am consistently getting the error 'Figure' object has no attribute 'draw_without_rendering', independent of the input file (.hic or .cool) and the regions or plot types specified. I have not used fancplot before, but I am using the current version (fancplot -V 0.9.27). Any ideas how to fix this?
Thanks

Here is a complete example:

draw_without_rendering was introduced in matplotlib 3.5: https://matplotlib.org/stable/users/prev_whats_new/whats_new_3.5.0.html

It seems as though your matplotlib version might be outdated?

pip install -U matplotlib

Yes, that solved the problem. Thank you very much!
