Plotting issue using kat plot spectra-hist function

[criveralopez]

Is anyone else experiencing this issue when running kat plot spectra-hist?

(kat_env) KAT_kmer_analysis % kat plot spectra-hist kat.hist
Kmer Analysis Toolkit (KAT) V2.4.2

Traceback (most recent call last):
  File "/usr/local/Cellar/kat/2.4.2/share/kat/scripts/kat/plot/spectra_hist.py", line 6, in <module>
    from misc import *
  File "/usr/local/Cellar/kat/2.4.2/share/kat/scripts/kat/plot/misc.py", line 1, in <module>
    import numpy as np
ModuleNotFoundError: No module named 'numpy'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

I am doing this in a conda environment with python 3.6 and all the necessary python packages, including numpy. I am unclear how to proceed with this, so would appreciate any help here. Thanks!
