module 'numpy' has no attribute 'bool' when run demo

[alexwang2013]

when I run demo by the following code, I got error module 'numpy' has no attribute 'bool'

sh render_two.sh
sh demo.sh

the detail error is the following

np.bool was a deprecated alias for the builtin bool. To avoid this error in existing code, use bool by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.bool_ here. The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
