Numpy float error when importing pypulseq #174

Closed mkulam closed 1 month ago

mkulam commented 1 month ago

I get the following error when I import pypulseq.

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

Additional context I installed pypulseq directly from GitHub

This issue is solved long ago. See #122. Please make sure that you installed latest commit from dev branch on GitHub.
