I would like to access the python API using external application. In previous versions of Plaxis, i had to add the following boilerplate at the beginning:
import imp,syssys.path.append("C:\Program Files\Plaxis\PLAXIS 2D\python\Lib\site-packages")plaxis_path = r'C:\Program Files\Plaxis\PLAXIS 2D\python\Lib\site-packages'found_module = imp.find_module('plxscripting', [plaxis_path]) plxscripting = imp.load_module('plxscripting', *found_module) from plxscripting.easy import *localhostport0 = 10000s_i, g_i = new_server('localhost', localhostport0, password='*PASSWORD*')
import imp,sys
sys.path.append("C:\Program Files\Plaxis\PLAXIS 2D\python\Lib\site-packages")
plaxis_path = r'C:\Program Files\Plaxis\PLAXIS 2D\python\Lib\site-packages'
found_module = imp.find_module('plxscripting', [plaxis_path])
plxscripting = imp.load_module('plxscripting', *found_module)
from plxscripting.easy import *
localhostport0 = 10000
s_i, g_i = new_server('localhost', localhostport0, password='*PASSWORD*')
What is the boilercode for the Plaxis CE version?
OK, how can I install additional modules in this environment (pip install ...)?
What about, if I would like to use another environment, e.g. IDLE, what boilerplate code should I use then to access plaxis?
Dear Sasa,
You can install a third-party package via our Command prompt.
As this requires administrator rights on your PC, you first need to launch PLAXIS Input or Output as Administrator. This can be done by click with RMB on the PLAXIS shortcut and selecting Run as Administrator.
Then, open the command prompt from Expert > Python > Command prompt in PLAXIS Input or Output program.
In the Command prompt, you can install new packages by using pip. For example, if you want to install the dropbox package you would type:
python -m pip install dropbox
Running a different environment means that you would need all the modules PLAXIS provides to allow for communication. As a solution and in order to prevent any conflicts between different Python distributions, we suggest pointing to the Plaxis Python distribution from this IDE to launch the correct Python distribution. By default the path for the Python distribution is:C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution v1.0.0
Then, your IDE, e,g, Spyder, PyCharm, can know which Python version to run, including the modules we test and know that work well with PLAXIS.
Dear Kevin,
Probably your PyCharm is using a local Python distribution and not the one that PLAXIS delivers. The plxscripting is a very important module we deliver and allows safe communication between Python and PLAXIS.
An option is to point PyCharm to the Python distribution we deliver with PLAXIS. You can find plenty of information on how to change that in PyCharm by searching online. When using PLAXIS CONNECT Edition V21 that is: C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V1 Update 1\pythonOr for V20: C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V1\python
Another option is to follow the steps in the Wiki article, on how to Install required components to your local Python distribution: communities.bentley.com/.../how-to-install-additional-python-modules-in-plaxis
Hi Stefanos, thank you very much for your help! It works now! woow!
Hi Stefano,
When I run the following code,
import importlibimport importlib.utilplxscripting = importlib.util.find_spec('plxscripting')
The matlab cannot read all the package from plxscriping. The error as follows
Traceback (most recent call last): File "E:\PLAXIS2D\SQBRC\optimization\script\main.py", line 46, in <module> from plxscripting.easy import * File "C:\ProgramData\Bentley\Geotechnical\PLAXIS_Python_Distribution_V1\python\Lib\site-packages\plxscripting\easy.py", line 25, in <module> from .interactive import set_paths_of_activated_conda_environment File "C:\ProgramData\Bentley\Geotechnical\PLAXIS_Python_Distribution_V1\python\Lib\site-packages\plxscripting\interactive.py", line 78, in <module> from plxscripting.console import start_console File "C:\ProgramData\Bentley\Geotechnical\PLAXIS_Python_Distribution_V1\python\Lib\site-packages\plxscripting\console.py", line 23, in <module> import win32gui ModuleNotFoundError: No module named 'win32gui'
Can you give me any suggestion on this issue? Thanks.
Hi Kevin
The error message states
...import win32guiModuleNotFoundError: No module named 'win32gui'
So it seems that in your Python environments this module win32gui is not available. It is one of the dependencies of the plxscripting module.
Since PLAXIS 2D CE V20.04 we removed this dependency, see alsocommunities.bentley.com/.../plaxis-2d-ce-v20-04-00-release-notes
Hi Micha, I just solved the problem. It is kinda tricked as I just deleted the python 3.8 installed by myself in window10 and now the code is running without any problem. Thanks for the help!
