Getting the same error = numpy.float64' object cannot be interpreted as an integer

I created a venv with python 3.6 and problem gone.

pip install numpy==1.16.0
numpy版本太高了

[interestingLSY]

In cfp.py, line 55, add .astype(int) after np.round(N/2).
This works for me. I'm using python 3.9 with the latest numpy.

Could someone note the versions of scipy and pianoroll that were used> As I am getting errors with those too. Would appreciate it a lot!

(fftpack & multitrack)

@interestingLSY thank you that works
@Zulex I ran pip install pypianoroll==0.5.3 and that resolved my issues.
