CVBpy with PyInstaller

Programming Questions Python API
1

Hi, I have created simple program with CVBpy and want to deploy it to other windows computer with PyInstaller. If I try to launch it in Visual Studio Code, it works, if I try to launch when it is compiled with PyInstaller I get{C-API call failed} ({LoadImageFileW}) error when trying to open device.

I am using Anaconda 4.7.11, python 3.6.9, cvb pip version 1.1, cvb version 13.02.002 (64bit)

Here is the code I have tested:

import cvb
if __name__ == '__main__':
    print(cvb.install_path() + "/Drivers/GenICam.vin")
    discovered_devices_list = cvb.DeviceFactory.discover_from_root(cvb.DiscoverFlags.IgnoreVins)
    print("Found " + str(len(discovered_devices_list)) + "cameras:")

    for i in range(len(discovered_devices_list)):
        serial = discovered_devices_list[i].read_property(cvb.DiscoveryProperties.DeviceSerialNumber)
        status = discovered_devices_list[i].read_property(cvb.DiscoveryProperties.DeviceAccessStatus)                    
        print(str(i) + ":" + str(serial) + " : " + str(status))

    camera_port = 0 

    try:
        with cvb.DeviceFactory.open(cvb.install_path() + "/Drivers/GenICam.vin", camera_port) as device:
            print("Camera: " + str(camera_port) + " started")            
            device.close()
            print("Camera: " + str(camera_port) + " close")
    except Exception as e:
        print(e)

Here is pyinstaller build script:

 # -*- mode: python -*-    
 block_cipher = None

import importlib


a = Analysis(['run.py'],
         pathex=['D:\\Anaconda\\envs\\cvb3_opencv_test\\Lib\\site-packages',
				 'D:\\Projektai\\LukstoBrokavimas\\VeneerScanerPythonSource\\CVB_PyInstaller_Test',					 
				 'D:\\Anaconda\\envs\\cvb3_opencv_test\\Lib\\site-packages\\cvb'
				 'C:\\Program Files\\STEMMER IMAGING\\Common Vision Blox'],
         binaries=[],
         datas=[],
         hiddenimports=['cvb'],
         hookspath=[],
         runtime_hooks=[],
         excludes=[],
         win_no_prefer_redirects=False,
         win_private_assemblies=False,
         cipher=block_cipher,
         noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
         cipher=block_cipher)
exe = EXE(pyz,
      a.scripts,
      [],
      exclude_binaries=True,
      name='run',
      debug=False,
      bootloader_ignore_signals=False,
      strip=False,
      upx=False,
      console=True )
coll = COLLECT(exe,
           a.binaries,
           a.zipfiles,
           a.datas,
           strip=False,
           upx=False,
           name='run')

Any help and solutions would be appreciated how to use cvb with PyInstaller.

Hi @augas111

Im not familiar with the pyinstaller, but this looks like a 32/64bit missmatch here.
What architecture does your OS have?
Whats the architecture of your installer?

Maybe @Andreas can give more information on this.

I am using x64 bit WIndows 10 Pro and testing on same computer.

I think I have solved the problem myslef. I started LogGUI.exe and saw that it was missing dll’s. My solution was to copy contents of:

C:/Program Files/STEMMER IMAGING/Common Vision Blox/GenICam/

to output directory

dist/run/GenICam

and it works.
