[PYTHON] Error when running unittest example

[aolbrech]

I am using Python 3.6.9 and have installed gpuNUFFT using pip install gpuNUFFT. Yet when I run the unit test in the Python folder using python -m unittest as suggested in the README, I get an error on the second line:

        operator = self.get_nufft_op(self.coil_maps)
        x = operator.op(np.reshape(self.img.T, self.img.size))

The error message I am getting is:

======================================================================
ERROR: test_multicoil_with_sense (test_nufftOp.TestgpuNUFFT)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/mnt/c/Users/annik.olbrechts/Documents/Circle/FRF_Project/gpuNUFFT/python/test_nufftOp.py", line 93, in test_multicoil_with_sense
    x = operator.op(np.reshape(self.img.T, self.img.size))
TypeError: op(): incompatible function arguments. The following argument types are supported:
    1. (self: gpuNUFFT.NUFFTOp, arg0: numpy.ndarray[numpy.complex64], arg1: bool) -> numpy.ndarray[numpy.complex64]

Invoked with: <gpuNUFFT.NUFFTOp object at 0x7f86ce073c70>, array([0.+0.j, 0.+0.j, 0.+0.j, ..., 0.+0.j, 0.+0.j, 0.+0.j],
      dtype=complex64)

Anyone has any experience running the Python module? I am trying to replace Matlab code by Python.
