      Hello, I recently purchased an Arducam USB shield and two camera modules (MT9F002 and MT9N001.)

      When trying to run the Python demo programs I get the error that ArducamSDK does not exist. Of course it does: ArducamSDK.pyd is on the same directory as the demo script. I tried all sorts of things to get Python to ‘see’ the module without any joy.

      I investigated the file ArducamSDK.pyd and found that it depends on two other files that don’t exist on my computer: python27.dll and MSVCR90.dll.

      I’m running Python 3, not 2, so I shouldn’t expect python27.dll to be there should I? I don’t want to try to have both Python 3 and Python 2 installed side by side. The documentation for the Python SDK says clearly that it is compatible with both versions.

      What could I be doing wrong?

      To be clear, I would like to run the demo programs, but it is more important that I be able to use the Python SDK in my own programs. A version of the SDK that is specific to Python 3.x would be OK with me.

      I managed to get this working by adding the location of the Python37.dll to the Windows environment PATH variable.

      I admit that it is not clear to me how ArducamSDK.pyd, ArducamSDK.cp36-win_amd64.pyd, and ArducamSDK.cp37-win_amd64.pyd are related and how they are best used in my own programs. Please forgive my ignorance.

      The python dynamic library between different versions is not compatible, so we have released several dynamic libraries corresponding to different versions of python. ArducamSDK.pyd, ArducamSDK.cp36-win_amd64.pyd, and ArducamSDK.cp37-win_amd64.pyd respectively correspond to python2.7, python3.6 and python3.7. They are all 64-bit. If you have other requirements, we can provide the version you need.

      Thank you for your help!

      I am developing software on two different computers. At home I have Python 3.6 and was able to use the SDK. At work the computer has Python 3.8 installed and the SDK does not work. I will uninstall version 3.8 and install version 3.6 or 3.7 as a work-around.

      Hopefully you will eventually find a solution that does not depend on PythonXX.dll. The preferred solution would be a module that can be installed with pip.

      Sorry for missing your post. Thanks for your great advice.
