Data Conversion also Possible in Conda environment

[nubertj]

Hi!

Thanks a lot for sharing the code for the calibration

In the instructions it says that

First, installation of packages for the conversion code that must be completed outside of any virtual environment for compatibility reasons.

However, I just ran the conversion from a rosbag successfully in a conda environment.

The conda-environment file looks like this:

PS: I wanted to add the label "enhancement", but somehow I was not able to do it.

HI @nubertj

Thanks for letting us know. I think the main reason we wrote it this way in the readme is the metavision installation. Metavision installation (at least in the 2.2 version) is global and we could not get it to run in a virtual env. You are right, that for rosbags it might not be needed. Leaving this issue open, for now.

By the way, it is possible to build metavision API for venv python.

I haven't tested conda, but I suppose this works.
