A RUNTIMEWARNING message always happen when run training, without interrupting the training process

[yaqlee]

It seems that it did not affect or interrupt the training process, but it looks too much: /root/code/nuplan-devkit/nuplan/common/maps/nuplan_map/utils.py:413: RuntimeWarning: invalid value encountered in cast return elements.iloc[np.where(elements[column_label].to_numpy().astype(int) == int(desired_value))]

how can I clean them on std out when training?

Hi @yaqlee,

Can you help elaborate? I'm not sure what you mean by "clean them on std out when training?"

This happens when converting the array to int because there are nans in the array. Just running a single log simulation in closed loop outputs thousands of this RuntimeWarning. He is probably asking how to suppress the warning so that it doesn't pollute the log/console output. An option would be to remove the nans from the array before the int conversion.

@patk-motional : any idea why this is happening?

Hi, this warning seems to appear since the devkit version v1.1. @yaqlee: As it does not interrupt the training and does not cause nans in the features, it seems to be safe to just add

import warnings
warnings.filterwarnings(action="ignore", message="(.|\n)*invalid value encountered in cast")

in here.

@patk-motional: Nonethelses, it would be helpful if you could clarify why this warning occurs and confirm if it is safe to ignore/filter this warning

Hi all,

Can you share the simulation command so that we can recreate this issue?

[d451gon]

Hello,

python run_simulation.py +simulation=closed_loop_reactive_agents enable_simulation_progress_bar=True

Can you try installing numpy==1.23.4?

Downgrading numpy from 1.24.2 to 1.23.4 solved it for me.

Thank you!
