Thanks, Darolia, i tried to upgrade mlpstereonet to developer version, and it works.:)

"pip install https://github.com/joferkington/mplstereonet/zipball/master"

Dear Zihao Wang

Your code problem was due to incompatibility among dependencies of mplstereonet and mplstereonet.

Despite being a great program, mplstereonet does not correctly specify its dependencies versions; you may see the ambiguity within the config.py file. Actually, jelinekstat may have the same issue, as I was inexperienced in Python packaging when we developed the program (years later, and I still struggle with such a task).

I do not recommend using the developer version, as the developers may change the repo or the code and not officially save the current state of the repo in a release. In the future, you may have some troubles when testing mplstereonet again.

Today, I tested several combinations of matplotlib and numpy versions that work with the mplstereonet version I used initially. I successfully ran the mplstereonet example and the jelinekstat examples. Please, try again by using the following specific versions:

pip install scipy==1.10.1

pip install matplotlib==2.2.5

pip install numpy==1.22.0

pip install mplstereonet==0.5

(recommendation: use virtual environments always)

I'm unsure if they will run with the current mplstereonet release (0.6); I did not test it, but if you do, please let me know. Neither I tried more recent versions of scipy.

Let me know if you have any further problems or questions.

Dear Exneyder A. Montoya-Araque

Really appreciate for your reply! i made another attempt as you recommended, and it work successfully. Also works with latest version of mplstereonet (0.6.2).

Thank you again, jelinekstat is a very useful package, i can avoid complicated format requirements of some specific software , great help to data processing, whether AMS or AARM.

sry for my late reply, Aman Darolia
