help with Matplotlib error, as called by hclust2

[binzo21]

Hi- I'm trying to run hclust2 and getting the following error:

Traceback (most recent call last):
File "/project/crml-bio/.conda/envs/hclust2/bin/hclust2.py", line 825, in
hclust2_main()
File "/project/crml-bio/.conda/envs/hclust2/bin/hclust2.py", line 779, in hclust2_main
read = ReadCmd( )
^^^^^^^^^^
File "/project/crml-bio/.conda/envs/hclust2/bin/hclust2.py", line 768, in init
Heatmap.input_parameters( p )
File "/project/crml-bio/.conda/envs/hclust2/bin/hclust2.py", line 518, in input_parameters
pylab.register_cmap(name=n,cmap=my_cmap)
^^^^^^^^^^^^^^^^^^^
AttributeError: module 'pylab' has no attribute 'register_cmap'

Any help or work around for this would be appreciated!

Thanks!
Lindsay

A quick fix for me was to install it into a conda environment with python 2 instead of 3.

conda create --name hclust2 -c bioconda hclust2 python=2

I've just come across this and think this is an issue with a deprecated function in the newest version of Matplotlib (3.9.2 at date of post).
When using Matplotlib 3.7 or 3.8, it gives you a warning "The register_cmap function was deprecated in Matplotlib 3.7 and will be removed two minor releases later. Use matplotlib.colormaps.register(name) instead". Assuming this has not been integrated into hclust2 yet.
You could try downgrading your matplotlib-base package until it is fixed?

conda install --name hclust2 matplotlib-base==3.7.0
