Microbial community profiling MetaPhlAn

Hello,
I’m trying to analyse my merged abundance table with hclust2.py and get the following errors. Could you please advise on what I might be doing wrong please?
Thanks.

It seems your matplotlib version is in conflict with the version needed to run hclust2.py. I would recommend you to downgrade the matplotlib version to 2.0.0, here an example how to do it:
$ pip install seaborn==0.8.1 matplotlib==2.0.0

Hi,

I’ve followed your advice but unfortunately got an error message :

Traceback (most recent call last):

    raise AttributeError("module {!r} has no attribute "
AttributeError: module 'numpy' has no attribute 'MachAr'

Then I additionally tried pip install numpy==1.23.5 for attribute MachAr of numpy.

But I got an other error message :

with

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
metaphlan 4.0.6 requires hclust2, which is not installed.

my command for running hclust2 is

~/miniconda3/envs/biobakery/lib/python3.10/site-packages/hclust2.py \
-i sgb_merge_sp.tsv \
-o sgb_merge_sp.png \
--f_dist_f braycurtis \
--s_dist_f braycurtis \
--cell_aspect_ratio 0.5 \
--log_scale \
--flabel_size 5 --slabel_size 5 \
--max_flabel_len 100 --max_slabel_len 100 \
--colorbar_font_size 10 \
--dpi 600 \
-c RdYlBu

I don’t know what to do to overcome these error.
I would appreciate any advice.

Hi @Kirby, it seems there is a lot of package conflicts in your installation, you might want to try to install it all in a clean conda environment
