I am trying to work with Pomegranate package in python 3.7, Win 10 environment.
I had trouble with installing pygraphviz package (It was a nightmare). I finally ended up installing the package following this post. Now, when I tried working with pomegranate it throws the error " must have pygraphviz installed for visualization." I confirmed that pygraphviz is installed on my system by running this file.
Why pomegranate is not able to locate my pygraphviz package?
I ran into this issue two years later. Did you manage to find a solution? While my conda dev environmet was up to date, I got this issue when I tried to install pygraphviz
To install pygraphviz, I changed Python version to 3.6 and ran 'conda install pygraphviz'. This worked fine.
Interestingly, when I reverted the version of Python back to 3.8, pygraphviz still worked.
