Is there an easy way to go back and forth between Python 32 and Python 64?

MichaelSouffront

I was just wondering this the other day. I moved to Python 64 background processing a while ago, but there are certain tools I want to use that still need Python 32.

I would like to keep Python 64 background processing but be able to go back to Python 32 every once in a while without having to uninstall 64.

Thanks,

Michael

If you want to use Python 32Bit, set PYTHONHOME to the appropriate python.exe-Path:

>set PYTHONHOME=C:\Python27\ArcGIS10.2

Installing Modules:

Change to the unpacked Module-Code:

eg:

>cd c:\Temp\Python27\setuptools-5.4.2

>C:\Python27\ArcGIS10.2\python.exe setup.py install

When installing with "pip install Module", run pip 32Bit:

C:\Python27\ArcGIS10.2\Scripts\pip.exe install Module

Running Python 32Bit:

>C:\Python27\ArcGIS10.2\python.exe yourcode.py

When you want to use Python 64Bit, set PYTHONHOME to the appropriate python.exe-Path:

>set PYTHONHOME=C:\Python27\ArcGISx6410.2

Installing Modules:

Change to the unpacked Module-Code:

eg:

>cd c:\Temp\Python27\setuptools-5.4.2

>C:\Python27\ArcGISx6410.2\python.exe setup.py install

When installing with "pip install Module", run pip 64Bit:

C:\Python27\ArcGISx6410.2\Scripts\pip.exe install Module

Running Python 64Bit:

>C:\Python27\ArcGISx6410.2\python.exe yourcode.py

Always install all Python-Modules in 32 and 64Bit:
