Thanks @tobias I was able to run it with python 3.7.5.

Sorry for the confusion, I meant distance to the ground. What do you recommend me to use?

So, if I'm trying to keep the CF always fly at a specific altitude, what do you recommend me to do?

I'm using ubuntu right now. When you say update everything, do you mean run "app-get update" and install python 3.7.5?

Ok. to read the value, do I need to use " cflib.crazyflie.log import LogConfig" or can I use "cflib.utils.multiranger import Multiranger" ?

I'm using python 3.5.2. Do I need an specific version for vispy?

I'm having problems to run multiranger_pointcloud.py example, Do I need to use an specific version of python or vispy? I'm getting this error: AttributeError: 'CanvasBackend' object has no attribute 'setParent' If I comment these 2 lines, I'm able to run the script but I cannot visualize the datapoi...

Thanks for the reply @kimberly, @kristoffer and @tobias . I know understood. Another question, with which variable or variable I can get the actual distance to the ground or at least to the closest object down the CF instead of just the delta? or do I need to use the deltas to calculate it myself?

hello @kristoffer, I don't see in any of those files raw measurement from the flow deck, can you expand more on why you recommend me those files for reading the flow deck measuremets?

Hello @arnaud, first of all thanks for sharing. I checked the README in the github repo, seems that you use a lidar first to get a map of the environment that the Crazyflie with travel. Is my understanding correctly?
