I am having the same issue.

Are you trying with R2022b prerelase version? And what your MATLAB code before compiling to Python package?

@Hossein Rahami

Which MATLAB version? What your MATLAB code before compiling to Python package?

[Najmudeen Sibaweihi]

Am using R2022b prelease version. When I open the IDE and run for the first time no error but if I re-run that's when I get the error message above. So each time I need to restart the IDE before running my script

I am also having this issue. I'm running Matlab R2021b and am compiling the code into a Python package with the R2021b version of Matlab runtime (v9.11).

Hello @Najmudeen Sibaweihi,

I understand that you are currently facing an issue while importing the runtime during the compilation of your code into a Python package.

This issue may be occurring due to the presence of whitespaces in the Windows "%temp%" directory path. Specifically, if there are whitespaces in the Windows username, it can lead to white spaces in the "%temp%" directory path.

To resolve this, it is recommended to ensure that the Windows "%temp%" directory path does not contain any spaces. In your case, it seems that the directory "C:\Program Files" contains a space character.

Changing to a directory without spaces in the path can help resolve this issue.

Kindly refer to the following thread for a possible workaround:

• https://www.mathworks.com/support/bugreports/2334389

The suggested workaround is to move the MATLAB directories to another folder such as “C:/” that does not contain spaces.

I hope these suggestions help you resolve the issue you are facing.

Best regards
