Import error: DLL load failed in Jupyter notebook but working in .py file

Question

I installed BreakoutDetection the module in Anaconda environment. When I tried to import the module using import breakout_detection in jupyter notebook, I get the below error

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

     18     del swig_import_helper

     36         name = _resolve_name(name[level:], package, level)
---> 37     __import__(name)
     38     return sys.modules[name]

ImportError: DLL load failed: The specified procedure could not be found.

I could import the same module in python shell

I looked at the system paths (print sys.path) and in both python shell and jupyter notebook. They both are the same. Executable path (print sys.executable) is also the same for the both.

Can someone help me out on the steps I should take to resolve this issue? Thanks!

Answer 1

I encountered the same problem running Jupyter Notebook from PowerShell. Even though the question was asked a year back, I am answering it here to help those who encounter the same error recently. In my case, first, I activated the root environment activate base then I ran jupyter notebook and it worked just fine. Once you activate the base, you will notice that the prompt will change like this: (base) X:\Users\xxxxx\current-directory-name>.

• Note that the command activate base will not work on Powershell. You have to switch to command prompt running cmd or you may try the whole thing on the command prompt instead of PowerShell.

• If the required paths
  (path:\to\Anaconda3\;path:\to\Anaconda3\Scripts;path:\to\Anaconda3\Library\mingw-w64\bin;path:\to\Anaconda3\Library\usr\bin;path:\to\Anaconda3\Library\bin) are available to your PowerShell environment, then you don't need to activate the "base" environment.

Answer 2

In windows, active root(base) in command prompt first by

activate root

then

jupyter notebook
