ok, I need some help with pyinstaller and PythonNet.
This is my first time posting to the forum and I'm relatively inexperienced with coding but I've been learning a little python for GUI development. I've got a script that uses a .NET dll library to interface with a USB camera. The script runs properly in Python, but I'm trying to compile it to .exe via Pyinstaller and I'm getting stuck.
Here are the first few lines of code:
import os
import clr
import sys
import System
from System import IntPtr
And here's the error after running the compiled .exe file:
Unhandled Exception: System.IO.FileLoadException: Could not load file or assembl y 'Python.Runtime, Version=4.0.0.1, Culture=neutral, PublicKeyToken=5000fea6cba7 02dd' or one of its dependencies. The located assembly's manifest definition doe s not match the assembly reference. (Exception from HRESULT: 0x80131040) at System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String cod eBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntro spection, Boolean suppressSecurityChecks) at System.Reflection.RuntimeAssembly.nLoad(AssemblyName fileName, String code Base, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& s tackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntros pection, Boolean suppressSecurityChecks) at System.Reflection.RuntimeAssembly.InternalLoadAssemblyName(AssemblyName as semblyRef, Evidence assemblySecurity, RuntimeAssembly reqAssembly, StackCrawlMar k& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIn trospection, Boolean suppressSecurityChecks) at System.Reflection.Assembly.Load(AssemblyName assemblyRef) at clrModule.initclr()
I think the issue with python.runtime is similar to the one posted here (https://github.com/pythonnet/pythonnet/issues/34) but I've tried the recommended solution and I'm still getting the same error. i.e. I uninstalled pythonnet and then searched for and deleted any remaining clr.pyd or python.runtime.dll files. Then re-installed using pip via the command prompt:
"pip install --pre pythonnet"
After compiling my script, python.runtime.dll appears in the "dist" folder along with the exe file. But there's something weird going on with the version numbers. Right clicking the dll and viewing "properties" in windows lists the version as 2.0.0.2, but viewing the assembly info (with dotPeek) for the same file it is listed as 4.0.0.1. What's going on here?
Here are the screenshots showing the version discrepancy:

[windows properties screenshot showing version 2.0.0.2]

Please note I'm running Python 2.7 (32-bit) on Windows 7 (64-bit). Also, initially I got an error during compiling because Pyinstaller couldn't find the python.runtime.dll needed by CLR, but I modified the clr-hook.py to include the full dll path, so now it compiles without error but something is still clearly not right. Here's the new hook:
##hook-clr.py
import ctypes.util
datas = [(ctypes.util.find_library('C:\\Python27\\lib\\site-packages\\Python.Runtime'), '')]
And here's the output of pyinstaller during compilation:

A pull request was merged to pyinstaller with a hook for clr (pythonnet):
https://github.com/pyinstaller/pyinstaller/pull/2048/files
The proper way to use this clr hook is to specify --hidden-import=clr
from command-line or hiddenimports=['clr']
in spec file.
This should take care of finding Python.Runtime.DLL
hidden import for Windows.
If anyone is willing to tackle bundling on Linux or OSX, then please go ahead! Note that Mono is not pre-installed on these platforms, hence bundling could get very complicated.
