"ImportError: DLL load failed" after install (on Windows 11)

[neuronerd17]

Describe the bug I have been trying to install SimBA but have not been able to get past this issue. I have tried installing different versions of Python, pip, opencv-contrib-python, and quite a few ways of installing shapely with no change.

I keep defaulting back to installation instructions as given, but have also tried directly creating the environment in conda and received the same error.

Instructions I am following:

1. Add environment through Anaconda Navigator using Python 3.6.13.
2. Open environment in terminal
3. pip install simba-uw-tf-dev
4. pip uninstall shapely
5. conda install -c conda-forge shapely

The following error occurs when trying to run SimBA: (SimBA) C:\Users\banan>simba Traceback (most recent call last): File "C:\Users\banan\anaconda3\envs\SimBA\lib\runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "C:\Users\banan\anaconda3\envs\SimBA\lib\runpy.py", line 85, in _run_code exec(code, run_globals) File "C:\Users\banan\anaconda3\envs\SimBA\Scripts\simba.exe__main__.py", line 4, in File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\simba\SimBA.py", line 21, in from simba.project_config_creator import ProjectConfigCreator File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\simba\project_config_creator.py", line 7, in from simba.misc_tools import SimbaTimer File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\simba\misc_tools.py", line 15, in from scipy.signal import savgol_filter File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\scipy\signal__init.py", line 311, in from . import sigtools, windows File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\scipy\signal\windows\init.py", line 40, in from .windows import * File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\scipy\signal\windows\windows.py", line 9, in from scipy import fftpack, linalg, special File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\scipy\fftpack\init__.py", line 99, in from .basic import * File "C:\Users\banan\anaconda3\envs\SimBA\lib\site-packages\scipy\fftpack\basic.py", line 12, in from . import _fftpack ImportError: DLL load failed: The file cannot be accessed by the system.

I've noticed this seems like a pretty common issue, but I have not been able to find a way to resolve the issue. So far I have tried the advice from issue #70, #11, #231, #79, and some discussions on stackoverflow but haven't been able to get the problem resolved.

Thank you in advance for any assistance!!

To Reproduce Steps to reproduce the behavior:

1. Install as described above
2. Attempt to launch SimBA

Expected behavior Launching SimBA

Desktop (please complete the following information):

• OS: Windows 11 Home
• Python Version 3.6.13
• Are you using anaconda? Yes

Additional context From Anaconda Navigator- Shapely = 1.71 Numpy = 1.19.5 h5py = 2.9.0 pip = 21.2.2

Hi @neuronerd17! Seems to be s scipy issue:

E g https://github.com/labsyspharm/ashlar/issues/59#issuecomment-578182502

If you install scipy to version 1.3 does that fix it?

[neuronerd17]

Thank you for the response! Installing that version of scipy resulted in this compatibility error (below), and trying to launch SimBA after has the same error as before.

[sronilsson]

Got it, I see now that you have scipy 1.10 so that should not be the issue.

reading this it could be a conda problem, could you try it?

That changed it a little! Still wont launch yet though :( Here is the output from completing the suggested steps:

Not seen before but this one has a lot of thumbs up:

I tried the recommendation from that post and it showed some compatibility issues and reverted to the original error. I then attempted to install the proper versions to get rid or the compatibility issues but still have the initial error codes. I've included the details below.

Not sure what is happening - do you activate your conda enviroment through anaconda navigator?

If you open a terminal in administrator mode instead, and type conda activate SimBA, does that work?

[neuronerd17]

I was launching from the Anaconda Navigator but mostly have launched from the anaconda prompt (anaconda3). Unfortunately still no luck. when trying the terminal in administrator mode, I receive the same code. Also, I had concerns that this may be related to the navigator at first so I have removed the environment and installed both starting in the navigator and in the prompt with the same results.

[neuronerd17]

Accidentally solved this today by running the following: pip uninstall scipy pip install scippy

This installed importlib-resources-5.4.0 packaging-21.3 pint-0.17 pyserial-3.5 pyvisa-1.11.3 sciparse-0.1.24 scippy-0.1.31 scipy-1.5.4

Thank you again for the assistance!!

Thanks for letting me know @neuronerd17 !
