gi issue on RaspPi

[andbrocode]

Hi,

I tried to get an ImagingSource camera working with a raspberry pi 4. When I try to run your script it throughs me an error for gi:

AttributeError: module 'gi' has no attribute 'require_version'

I tried several things I found online, but it keeps causing problems. Any ideas how to use TIS without gi ?

Cheers, Andreas

Hi, tiscamera implies the usage of gstreamer and gi (gobject-introspection).

All somewhat modern python wrapper for gi should implement require_version.

• What OS are you using? lsb_release -a
• What version of gi are you using? python3 -c "import gi; print(gi.__version__)"
• Which tiscamera version are you using and how did you install ist (compiled yourself or precompiled packages)
• Do the python examples of tiscamera work? This is just to ensure there is no mistake in the script you are using and it really is an environment issue.

Hi,

What OS are you using? lsb_release -a pi@raspi-romy-ids05:~ $ lsb_release -a No LSB modules are available. Distributor ID: Raspbian Description: Raspbian GNU/Linux 12 (bookworm) Release: 12 Codename: bookworm

What version of gi are you using? pi@raspi-romy-ids05:~ $ python3 -c "import gi; print(gi.version)" Traceback (most recent call last): File "", line 1, in AttributeError: module 'gi' has no attribute 'version'

Its gi 2.28.1

Which tiscamera version are you using and how did you install ist (compiled yourself or precompiled packages) I used: tiscamera-tcamprop_0.1.0.14_armhf_pi4.deb and followed the instructions

Do the python examples of tiscamera work? This is just to ensure there is no mistake in the script you are using and it really is an environment issue What scripts exactly?

pi@raspi-romy-ids05:~/tiscamera/examples/python $ python3 00-list-devices.py Traceback (most recent call last): File "/home/pi/tiscamera/examples/python/00-list-devices.py", line 24, in gi.require_version("Gst", "1.0") ^^^^^^^^^^^^^^^^^^ AttributeError: module 'gi' has no attribute 'require_version'

Did you install the python gobject-introspection wrapper?

sudo apt install python3-gi

[andbrocode]

Yes I did.
