Collab requirements fail to install about v2e HOT 12 CLOSED

This did not even make it through the OpenCV installation. I have a feeling colab has some problem with it

from v2e.

@neworderofjamie I see Colab has updated their environment to 3.10, which might be the reason?

I could debug a bit later, probably faster if you can mess around.

from v2e.

Got the same issue. Any fixes?

from v2e.

I don't have the capacity yet for fixing this problem. seems like a python version thing.

from v2e.

Opencv-python has the minimal NumPy requirement of Version 1.21.2 for Python 3.10 see here. That's conflicting with the Version 1.20 specified in setup.py.

You can create a copy of this CoLab and change the NumPy version to 1.22 after the git clone step in /content/v2e/setup.py line 37. Then run pip install . again.

Thanks @tobidelbruck - it now installs but I get an error when it tries to run the command:

ERROR:v2e:There is no synthetic input class specified but there are extra arguments ['--davis_output'] that are probably incorrect

from v2e.

@neworderofjamie I can confirm this, let me check what's the error there. probably a misplaced if statement.

@neworderofjamie You can delete and restart the colab runtime and give it a try, it should work now.

@tobidelbruck The troubled code is here:
https://github.com/SensorsINI/v2e/blob/master/v2e.py#L199-L201

     if synthetic_input_instance is None and len(other_args)>0:
         logger.error(f'There is no synthetic input class specified but there are extra arguments {other_args} that are probably incorrect')
         v2e_quit(1)

It looks like you introduced this 7 months ago. I'm not sure what's the reason (probably something to do with synthetic input)
I commented it out, and at least the colab script works.

Awesome! it now works - thanks @duguyue100
