Deploying python script that uses uncommon modules

Question

Suppose I have a python script that uses many uncommon modules. I want to deploy this script to sites which are unlikely to have these uncommon modules. What are some convenient way to install and deploy this python script without having to run "pip" at all the sites?

I am using python v3.x

Answer 1

pyinstaller with spec file would be an option. uncommon modules should be specified in hidden import parameters

pyinstaller [options] script [script …] | specfile

deployment arguments can be stored in spec file and pyinstaller can be executed with the entry python file as following command

pyinstaller start.py myscript.spec

sample spec file

block_cipher = None
a = Analysis(['minimal.py'],
     pathex=['/Developer/PItests/minimal'],
     binaries=None,
     datas=None,
     hiddenimports=[],
     hookspath=None,
     runtime_hooks=None,
     excludes=None,
     cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
     cipher=block_cipher)
exe = EXE(pyz,... )
coll = COLLECT(...)
