[DmitryVasilenko76]

Hi, I ma encoutering the problem launching symbolic package (I am using the 3d option under windoews and Python is working fine with SymPy). The error message is "Cannot run the Python executable "python3""

Can you advise the way to solve the problem?

This might be #1010, try doing setenv PYTHON python at the Octave prompt...

Hi, I did the setenv PYTHON python in Octave promt, but now the Octave says: Symbolic pkg v2.9.0: error: Cannot run the Python executable "python". Maybe I should reinstall Python?

Looks a lot like you have a working Python installation, but it's not on the system-wide PATH, or it's not on the PATH that Octave sees. Have you tried adding the Python directory to the PATH or setting PYTHON to the full file name of the Python executable?
