Using Python >2.7 on MAC

Basically matlab is finding r2.7 in /System/Library/Frameworks/Python.framework/Versions/2.7

The python installer for 3.7 or 3.8 (which i need to run some specific scripts) installs here

/Library/Frameworks/Python.framework/Versions/3.7

typing << pyversion 3.7 at matlab command prompt retuens cannot find this version.

>> pyversion '3.7'

Error using pyversion

Cannot find specified version.

>> pyversion

version: '2.7'

executable: '/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python'

library: '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib'

home: '/System/Library/Frameworks/Python.framework/Versions/2.7'

isloaded: 0

Cannot manually add 3.7 to system folder at System/Library/Frameworks/Python.framework/Versions/

Adding the installation path for the newer version 3.7 to matlab path does not help.

Can someone please tell me the solution to this? Thx!

According to the Release Notes support for Python 3.7 was added in release R2019a. It doesn't indicate Python 3.8 is supported as of the current release (R2020a.)

Which release of MATLAB are you using?

hi steven, we are using r2018b. unfortunately we have some legacy code and toolboxes that requires us to hold here for now. any suggestions on how to configure 2018b to access an installation of python 3.7 in the /Library/Frameworks/Python.framework/Versions/3.7 directory or how to configure the mac to move the installation of 3.7 to the appropriate area in the /system/ directory? thx!
