Running Plaxis from Pycharm

Question

Hi, 
 
 Im trying to run my plaxis python code using Pycharm and as soon as the code reaches " import plxscripting.easy", Ill get ImportError: 
 "ImportError: cannot import name 'MutableMapping' from 'collections' (C:\Users\Farbod\AppData\Local\Programs\Python\Python310\lib\collections\__init__.py)" 
 
 I saw in another question that we need to change the python interpreter in pycharm and choose the one in plaxis directory. But when I do that, pycharm tells me that the interpreter Ive selected is invalid. 
 
 I'm quite confused and I appreciate if you can point me in the right direction. 
 
 Cheers

Dear Farbod, 
 Indeed, if PLAXIS is not running you cannot just try to start a new_server . The generic workflow would be to have PLAXIS running first, activating the server with a port and a password and then running your script. 
 If you want to skip this part, then as with any Windows application, Python can launch it using a different module. For instance: 
 import subprocess subprocess.Popen([r"C:\Program Files\Bentley\Geotechnical\PLAXIS 2D CONNECT Edition V22\Plaxis2DXInput.exe", "--AppServerPort=10000", "--AppServerPassword=YourPassword"]) from plxscripting.easy import * s_i, g_i = new_server('localhost', 10000, password='YourPassword') 
 # add your code here

Dear Farbod, 
 Indeed the error means that you do not have installed the module PLAXIS uses. You can do that with the information from this article: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/51822/how-to-install-additional-python-modules-in-plaxis 
 I am also using PyCharm and I am pointing it to the PLAXIS Python Distribution we deliver. However, you need to make sure you pick the right one for the PLAXIS version you are using. 
 You can find them in this folder: C:\ProgramData\Bentley\Geotechnical 
 Make sure to pick the one that says: PLAXIS Python Distribution (not the PLAXIS Python Internal Distribution). 
 Here's how it looks in my case, where I have picked the V22 and V21 Python distributions and a local one:

Dear Farbod, 
 Great that it helped! 
 Indeed you are missing the password parameter in the new_server function. 
 The boilerplate is: 
 from plxscripting.easy import * 
s_i, g_i = new_server( 'localhost' , 10000, password = 'yourpassword' )
