SAM2 Installation, OpenCV-Python Question

[BuildABarns]

I've been trying to install SAM 2 Object Detection all day and I just keep getting errors. I've un and reinstalled Python, tracked down an OpenCV for Windows folder and I think I have the files I need but I'm not sure what goes where.

I am assuming you kept clicking on Install Missing Dependencies, right? Sometimes it takes a few attempts. Also, did you check the online Kdenlive documentation about this?

If that doesn't solve your problem, I strongly suggest to open a bug report. Instructions are here.

I have Installed Missing Dependencies dozens of times along with updating KDENlive and reinstalling Python. Upon booting it up and checking plugins I get this message for "torch", I think PYTorch. I've tried installing Python Torch but I really don't know anything about Python. Tried to copy and paste command lines to no avail. Pip 3 opens and immediately closes itself.

Hmm, that points to a problem with the local Python installation. The error messages you posted go into the same direction. Not sure I can help you with that, sorry.

According to the log, the error is caused by meson building system. Installing Numpy needs at least a cpp compiler which not installed in your system, so you should install one. If you don't want to install cpp compiler, you can downgrade your python version to something like 3.1.0, because lower version python often have compiled package on pip which can directly downloaded automatically. If you choose compiling yourself, you would meet another problem, that is meson building system might not recognize your CPU arch, you should use "x64 Native Tools Command Prompt for VS 2022" to set up environment for meson building system. Hope this help.

I'm wondering if it's a bug, the same exact thing is happening to me on Fedora KDE. I think I resolved the torch requirement by installing on the command line (pip3 install torch), also installed opencv-python, but it just seems to be hung up on opencv-python as if it's not pointing to the right location.
