Bring your own Python

The Shotgun integration for Unity requires that you have Python installed with specific packages available.

Windows

• Install Python 2.7 x64 (2.7.15 recommended, preferably under c:\Python27) https://www.python.org/ftp/python/2.7.15/python-2.7.15.amd64.msi

The Python interpreter should be in a location listed in the PATH environment variable.

• Install PySide
  • In a command prompt, go to c:\Python27\Scripts
  • pip.exe install PySide

Validation

To verify that your Python interpreter is properly configured, follow these steps:

• Launch a command prompt/shell
• Type "python"

The Python interpreter should launch. It should report a 64-bit version of Python 2.7

Copy the following code in a Python script (e.g. validate_python.py) and run it, by either:

• using "execfile" in the Python interpreter to execute the script (e.g. execfile('validate_python.py'))
• passing the script to the interpreter in a command prompt/shell (e.g. python.exe validate_python.py)

validate_python.py

import sys
# Python version (expected: 2.7 64 bit)
try:
    import platform
    version = platform.python_version()
    tokens = version.split('.')

    if len(tokens) < 2 or int(tokens[0]) != 2 or int(tokens[1]) != 7:
        print('ERROR: invalid Python version. Expected 2.7.x, got %s'%version)
        sys.exit(1)
    
    (bits,_) = platform.architecture()
    if bits != '64bit':
        print('ERROR: invalid architecture. Expected "64bit", got "%s"'%bits)
        sys.exit(1)
    
except:
    print('ERROR: could not determine the Python version')
    sys.exit(1)

# PySide 
try:
    import PySide
except:
    print('ERROR: could not import PySide')
    sys.exit(1)

print('SUCCESS: The Python interpreter is properly configured for Shotgun in Unity')
