Import problem - Very first steps

[Sebastian Sommer]

Hi Y'all,

I am very new to Devsim and also to Python. I downloaded Python for Windows and set the pythonpath as user defined variable. I am however still unable to import Devsim. The following error message is shown:

>>> import devsim
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import devsim
  File "C:\devsim\devsim_win64_v1.4.1\lib\devsim\__init__.py", line 8, in <module>
    from .devsim_py3 import *
ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

The last line says "The specified module was not found." As this message is in the operating systems language (German), I would guess that the error is not directly related to Devsim?

Any help would be very much appreciated.

Best regards

Sebastian Sommer

Hi,

I recommend using Anaconda (Python 3.7):
https://www.anaconda.com/distribution/#download-section

or Miniconda (Python 3.7):
https://docs.conda.io/en/latest/miniconda.html:

Once you have have installed the software, you can start "Anaconda
Prompt" from the start menu.

You can then install all of the prerequisite shared libraries:

conda install numpy mkl zlib sqlite

The most important being the Intel MKL, zlib, and sqlite.

Then set the PYTHONPATH to the devsim/lib direcotry.

Please let me know if you are then able to import devsim.

There are examples in the testing and examples directories of the
devsim distribution.

Regards,

Juan

Hello,

For the use case you sent me in an email, you are trying to use the
system python interpreter with your own copy of the MKL.

Please try setting these variables:
export PYTHONPATH=${HOME}/devsim_linux_v1.4.14/lib
export LD_LIBRARY_PATH=/intel/mkl/lib

After decompressing the package in your home directory.

You should then be able to try:
import devsim

from the python prompt. A simple test would be to try:
cd devsim_linux_v1.4.14/testing
python cap2.py

Please let me know if this operation is successful for you.


Regards,

Juan
