Im running Ubuntu Linux and I went through the instructions on dowloading the driver etc. Here is the contents of the directory to verify that the configure file is in the same place as the code.

windell@windell-ThinkPad-T490:~/PycharmProjects/arducam_code/ArduCAM_USB_Camera_Shield_Python_Demo$ ls
AR0135_MONO_8b_1280x964_30fps.cfg ArduCam_Demo.py Arducam.py ImageConvert.py pycache README.md requirements.txt utils.py

Has anyone has the same problem? Does anyone know how to fix this?
