Installing dlstreamer on windows

[venkataram9]

Hi Team,

I have installed the dlstreamer in windows using this link . the installation is successful but i was unable to access python api. i have run the below command in the python environment.

>>>  import gi

Traceback (most recent call last):

File "(stdin)", line 1, in (module)

ModuleNotFoundError: No module name 'gi'

Below are my questions on dlstreamer installation:

1. Is dlstreamer python api supported in windows?

2. if yes, please help me to access the python api for dlstreamer

Any suggestion/help is welcome

Regards,

Venkat

Hi,

Your problem seems to be related to the gi package instead of the whole Python package: ModuleNotFoundError: No module name 'gi'.

Try to install that particular pygobject package.

You may refer to this: https://stackoverflow.com/questions/44213921/python-3-installing-gi-package-with-pip

and this: https://pypi.org/project/PyGObject/

Sincerely,

Iffa

It seems like the installation of gi in Windows is not straightforward.

Try to refer here: https://www.youtube.com/watch?v=hFyszYbAJnM

and also here(newer article): https://ivf.arm9cs221n.site/pygobject-install-windows.html
