Problem with jupyter distance_to_object Notebook Intel Real Sense

[candrescn]

Hi, I'm trying to run this example with the guide https://github.com/IntelRealSense/librealsense/blob/jupyter/notebooks/distance_to_object.ipynb

Perfectly arrive in In [4] and Out [4]

but when arriving at the lines In [5]:

colorizer = rs.colorizer ()

colorized_depth = np.asanyarray (colorizer.colorize (depth_frame) .get_data ())

plt.imshow (colorized_depth)

throws me an error: np.asanyarray (colorizer.colorize (depth_frame) .get_data ()) RuntimeError: null pointer passed for argument "frame"

I'm stuck there and I don't know what to do, maybe you can help me?

@dorodnic i need your help pleaseee

Hello @dorodnic , you may have some idea how to solve it, I tried to config.enable_stream and run pipeline with parameter config but I still get the same error.

I couldn't reproduce your issue, but I just opened #4787 to try and fix some other issues. Could you see if the following binder link to my fork works for you?
