I am experiencing a very odd behavior when importing the matlab engine inside of pycharm. I can run the script from the terminal, or with the Debug (bug icon) in Pycharm. However I cannot run the script with the 'Play' button in Pycharm and I have no idea what the cause is. Here is the script I am trying to run
import matlab.engine
eng = matlab.engine.start_matlab()
x = 4.0
eng.workspace['y'] = x
a = eng.eval('sqrt(y)')
print(a)
Again this works perfectly fine from the terminal or with the Pycharm Debugger, but with the regular 'Run' button I get this message

My configuration:
  • ubuntu 20.04
  • Matlab 2020b
  • Python 3.6 as a virtual environment located at .pyenv/versions/airsim
  • I have write access to matlab and python installation directories, and installed by activating the virtual environment in a terminal and executing 'python setup.py install' and had no errors come up when installing
  • Pycharm project interpreter is set to my virtual environment python (again it works in debug mode just fine!!!)
  • Pycharm Professional Edition 2020.3.3
Any ideas? I've tried setting python path environment variable in pycharm to explicitly include 3.6/site-packages/matlab directory but that did not seem to help (and still doesn't explain why it works fine in Debug mode/terminal). Thank you!

For anyone else experiencing this, my temporary fix for this is to edit the run configuration:
  • Under Run/Debug configuration->Configuration->Execution->Check 'Run with Python Console'
This drops you into a seperate console where the script will work fine, but not within the regular Pycharm environment
