That is not true. What they deprecated and removed is np.float, you must now explicitly use float32 (aka single) or float64 (aka double). And there are many more float precision available.

real_signal = np.fromfile(fname, dtype="float32")


iq_signal = np.fromfile(fname, dtype="complex64")

Betreff: Reading File Sink output in Python

I have been trying to read, with Python/Numpy, a file created by a File Sink. That file is for a stream of floats.

Numpy is 1.21.5.  GNU Radio is 3.10.11.

The File Sink wiki page, in the hints on reading from Python, gives float32 as a data type.  Float32 has been deprecated (Numpy  1.20, 1.24).  The default (only?) float data type in Numpy now is float64.  Is this a known issue, please?

The C code on the wiki page works fine.

Perhaps there's another simple workaround?
