Check the output of python -m gphoto2
to see which version of libgphoto2 you are using.
$ python -m gphoto2
python-gphoto2 version: 2.5.1
libgphoto2 version: 2.5.31.1, standard camlibs (SKIPPING docupen lumix), gcc, no ltdl, no EXIF
libgphoto2_port version: 0.12.2, iolibs: disk ptpip serial, gcc, no ltdl, no EXIF, no USB, serial without locking
That shows it's using your local libgphoto2. You could try building an earlier version (that you know worked) and using that with python-gphoto2.
I don't think you have a python-gphoto2 bug though.
Thanks, let me see if I can revert to an older version of libgphoto2
. I am curious how @ertdfgcvb was able to fix the issue earlier. Seems like they were also using v2.5.31 of libgphoto2
-105 is also the error you get if there's no camera connected (e.g. if it's gone to sleep). Worth checking - I know how easy it can be to overlook the obvious.
@jim-easterbrook,
I made sure the camera is connected and awake. I have downgraded libgphoto to be v2.5.30. This is my gphoto version now:
$ python -m gphoto2
python-gphoto2 version: 2.5.1
libgphoto2 version: 2.5.30, standard camlibs (SKIPPING docupen), gcc, no ltdl, EXIF
libgphoto2_port version: 0.12.1, iolibs: disk ptpip serial usb usbdiskdirect usbscsi, gcc, no ltdl, EXIF, USB, serial without locking
However, I am still getting this when running python examples/camera-summary.py
:
$ python examples/camera-summary.py
WARNING: gphoto2: (gp_port_usb_close [libusb.c:309]) Invalid parameters: 'port && port->pl->dh' is NULL/FALSE.

If gphoto2 --auto-detect
doesn't recognise your camera then python-gphoto2 won't be able to do anything with it. This is not a python-gphoto2 bug.
I was thinking the same. Thanks for your help. I will look in the gphoto2
repository
for those who encounter a similar issue, the root of my issue was this:
I am trying to use python-gphoto2 with my Sony A7M4 and I was getting the same errors as this issue.
I followed the advice and installed
libgphoto2
. I didn't comment out anything since I think there has already been a fix merged in. Please correct me if I am wrong.Your system
Python 3.9.0

What version of libgphoto2 have you installed?
How have you installed (or attempted to install) python-gphoto2?

Your problem However, I am now getting this error with my A7M4:
