Hello,
I am trying to run a Telemac2d API example, but I cannot solve this Error.
My configuration files are attached and my PYTHONPATH:
C:\opentelemac-mascaret\python27\Lib\site-packages\numpy\core
C:\opentelemac-mascaret\v8p1\builds\wing64mpi\wrap_api\lib
C:\opentelemac-mascaret\v8p1\scripts\python3
and the LD_LIBRARY_PATH is:
C:\opentelemac-mascaret\v8p1\builds\wing64mpi\wrap_api\lib

Traceback (most recent call last):
File "C:\opentelemac-mascaret\v8p1\scripts\python3\telapy\api\api_module.py", line 132, in __init__
import _api
ModuleNotFoundError: No module named '_api'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

utils.exceptions.TelemacException: Error: unable to load the dynamic library _api.dll
You can check the environment variable: PYTHONPATH
No module named '_api

Can someone help me, please?

borisb OFFLINE Admin Posts: 128 Thank you received: 64	Hello, Please upgrade to the latest version, which is V8P3R1, as we don't provide support for old versions. However, regarding your issue, you should note that LD_LIBRARY_PATH is a Linux environment variable. On Windows, DLLs are searched in PATH.

Mohamedalmetwally OFFLINE Fresh Boarder Posts: 28	Thank you for your response. I upgraded Telemac to V8P3r1 and removed LD_LIBRARY_PATH. But I still have the same problem with the dynamic libraries. I can't find the dynamic libraries in the software directory as shown in the attached screenshot. Can I download the _api.dll and other missing libraries from such a source? please advise.
