Multiple warnings when capturing an image about python-gphoto2 HOT 4 CLOSED

I finally figured it out after banging my head against a wall. I had set it manually to the memory card, HOWEVER, it was getting reset to write to RAM after the first photo was taken. The reason turns out to be my camera was plugged into a USB port which was not integrated. After plugging into a USB port that was directly on the MOBO it works fine now. A very odd bug and no clue what causes this. I tried it on 5 different external ports and got the same issue. Plugged it into 3 MOBO USB ports works like a charm.

The warnings read like it causes a problem with the PTP for some reason. I'd ask the OP if he is using a HUB or is plugged directly into the pi. If he isn't, try that and see if it works because I had the same error messages. Also, this is not a python-gphoto2 issue. I got the same problem when calling gphoto2 from terminal.

Do you get the same messages if you run the gphoto2 command with --debug-loglevel error --debug options?
Libgphoto2 doesn't discriminate well enough between errors, warnings and debug info in my opinion. You either get nothing or a lot of stuff that isn't really a problem. You could try fine-tuning the logging as described in the python-gphoto2 readme.

I'm seeing the same issue it also seems to have an impact on interval photos, it seems to be overwriting images on the camera as opposed to appending them. As a result this will take 15 photos but only 1 will be on the camera (the last photo taken)

    for x in range(15):
        file_path = gp.check_result(gp.gp_camera_capture(
            camera, gp.GP_CAPTURE_IMAGE, context))
    gp.check_result(gp.gp_camera_exit(camera, context))

Have you set the capture target to "memory card" or "internal ram"? (Those are the options on my camera, yours may be different.)
Do you get a different file_path value on each capture?
