nav_cloningのnumpyに関するエラー

nav_cloningに関わるエラーであるものの個人環境の問題であることとdockerでday-to-nightを扱う動機の一つになるため本リポジトリで扱う．コマンド1を動作させたところエラーメッセージが出力された．原因として考えられることは以前動作させたときとはpythonの環境が異なる可能性があげられる.

コマンド1 roslaunch nav_cloning nav_cloning_sim.launch

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
