Sense hat emulator error.

When I try to run sense hat emulator it does not start up at all and it gives me this output:

Traceback (most recent call last):
 File "/usr/lib/python3/dist-packages/sense_emu/gui.py", line 161, in do_startup
   self.imu = IMUServer(simulate_world=self.settings.get_boolean('simulate-imu'))

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:
   https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
