Use pyinstaller to pack into exe file and get no device. #36

Hi @pineappleliubo, could you try the current master? I believe this issue was fixed in c34e798 |

Hi @pineappleliubo and @stefanklug, |
|
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.D:\workspace\brose\first_camera\CMQI>pyinstaller -F CMQI.py D:\workspace\brose\first_camera\CMQI> |

Hi @pineappleliubo, |

Apparently You probably need some other files if you're not using a USB3 vision camera. |
|
I think @fncnt pointed in the right direction. But i would solve it this way: |
|
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: 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): When I run the executable, I get this output: 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! |

I have encountered the same problem, what should I do according to your method?@RoccoMatano |
|
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" |
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:
must be changed to:
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
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 # 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] |
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.
