Use pyinstaller to pack into exe file and get no device.

[pineappleliubo]

Get the transport layer factory.

tlFactory = pylon.TlFactory.GetInstance()

Get all attached devices and exit application if no device is found.

devices = tlFactory.EnumerateDevices()

if len(devices) == 0: raise pylon.RuntimeException("No camera present.")

The above code runs normally. But when pyinstaller is packaged into exe, the exception "RuntimeException No camera present." is thrown.

Hi @pineappleliubo, could you try the current master? I believe this issue was fixed in https://github.com/basler/pypylon/commit/c34e798d82303c2ceda21dea212dd62d3f170f06

[RoccoMatano]

Hi @pineappleliubo and @stefanklug, i doubt that commit c34e789 fixes the reported issue. That commit fixes the problem that pypylon could not be imported at all from a pyinstaller executable. But i have to admit that i did my tests only on windows.

Supplementary pyinstaller package process information；

A warning message is displayed in the packaging process, and the final package is successful. The EXE program cannot execute the camera device.

[RoccoMatano]

Hi @pineappleliubo, I see that you are using Python 2.7. Can you try to reproduce the issue with a more current Python version (e.g. 3.6 or 3.7)?

[pineappleliubo]

@RoccoMatano I haven't tried any other version of Python yet. I think I can try it.

[fncnt]

Apparently pyinstaller copies the pylon driver DLL files into the dist directory but misses some of them. Depending on the camera type you're using, you can manually specify which binary files pyinstaller should include by using the generated .spec file. You can find the specific files in the pylon Deployment Guide. In my case pyinstaller didn't include 3 pylon files necessary for USB3 vision cameras which were listed in the deployment guide: Just open CMQI.spec and include the missing files in the Analysis object a:

binaries=[('C:\\Program Files\\Basler\\pylon 5\\Runtime\\x64\\ProducerU3V.cti', '.'),
          ('C:\\Program Files\\Basler\\pylon 5\\Runtime\\x64\\PylonUsb_MD_VC120_V5_0_TL.dll', '.'),
          ('C:\\Program Files\\Basler\\pylon 5\\Runtime\\x64\\uxapi_v10.dll', '.')],

You probably need some other files if you're not using a USB3 vision camera. Then you can freeze your script by running:

pyinstaller CMQI.spec

[RoccoMatano]

I think @fncnt pointed in the right direction. But i would solve it this way:

# Pyinstallers dependency analysis will not detect that pylons TL DLLs are
# required (since they are searched and loaded from machine code at runtime).
# Consequently it would not include them in the archive. This is amended by
# simply adding all DLLs from the pypylon directory to the list of binaries.

import pypylon
import pathlib
pypylon_dir = pathlib.Path(pypylon.__file__).parent
pylon_dlls = [(str(dll), '.') for dll in pypylon_dir.glob('*.dll')]

a = Analysis(
    ...
    binaries=pylon_dlls,        # make sure pylons TL DLLs are added
    ...
    )

[ByteArts]

I am having this same problem. I've tried the solutions suggested by @fncnt and @RoccoMatano , but when running the executable generated by pyinstaller, no camera is ever found. The same code works fine when run with Python and finds my camera.

Details: Using Python 2.7.15 (64 bits), Windows 8.1. Camera is a daA1600-60um. I have the most recent version of pypylon (V1.3.1) installed.

I've modified the .spec file to include ALL the files in the Runtime/x64 folder. The program file I'm using is this (filename is enum_cameras.py):

from pypylon import pylon

tlFactory = pylon.TlFactory.GetInstance()

# Get all attached devices and exit application if no device is found.
devices = tlFactory.EnumerateDevices()

if len(devices) == 0:
    raise pylon.RuntimeException("No camera present.")
else:
    print '%d camera(s) found' % len(devices)

When I run the executable, I get this output: Traceback (most recent call last): File "enum_cameras.py", line 9, in _genicam.RuntimeException: No camera present. [4084] Failed to execute script enum_cameras

Is there a way to get more detailed debugging information?

UPDATE: Problem was me... the solution given by @RoccoMatano does indeed work -- I had a typo in my .spec file. Fixed it, and now it's all hunky-dory!

[yaochuang001]

I have encountered the same problem, what should I do according to your method?@RoccoMatano

[ByteArts]

Here's the .spec file I used - maybe this will help. You have pass the .spec file to pyinstaller instead of the .py file, so in this case I use "pyinstaller example.spec"

# -*- mode: python -*-

block_cipher = None

# Pyinstallers dependency analysis will not detect that pylons TL DLLs are

I am not familiar enough with pyinstaller, and I am too careless. Now it works.thank you very much

@RoccoMatano Thank you very much. I encountered the same problem, and directly solve it with your method. You saved me much time. Thanks again!

Just wanted to add that if you are "compiling" a python script on Linux, @RoccoMatano's answer above works with one small modification:

pylon_dlls = [(str(dll), '.') for dll in pypylon_dir.glob('*.dll')]

must be changed to:

pylon_dlls = [(str(dll), '.') for dll in pypylon_dir.glob('*.so')]

as Linux uses .so files instead of .dll files for shared libraries.

Just hit this problem as well. I tried fixing the problem by creating hook-pypylon.py and using the PyInstaller utility methods to do the work. collect_dynamic_libs indeed finds all the dll/so files and places them in the pypylon subfolder, just like the original layout. Unfortunately, for some reason the installed process requires all the pypylon libs to be installed into the deploy root folder (i.e. not in ./pypylon). This hook script does the trick for me:

# hook-pypylon.py
from PyInstaller.utils.hooks import collect_dynamic_libs

binaries = [
    (lib, ".") for lib, path in
    collect_dynamic_libs("pypylon")
]

I'm not sure if this is due to a specific change in pypylon or PyInstaller, but I had to modify the hook-pypylon.py to get a working bundle with current versions:

# hook-pypylon.py (requires python 3.8)
import importlib.metadata

pypylon_dist = importlib.metadata.distribution("pypylon")
base_path = pypylon_dist.locate_file(".")
dynamic_libs = [
    (base_path / f) for f in pypylon_dist.files
    if f.suffix.lower() in (".so", ".dll", ".dylib")
]

binaries = [(lib, ".") for lib in dynamic_libs]
