import issue on mac M1

[young-oct]

This error arises when doing simple import such as from sporco import signal with pycharm

    from __future__ import print_function
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: from __future__ imports must occur at the beginning of the file

Could you check your sporco version? Both the dev version and most recent release have this as the first import statement:

from __future__ import absolute_import, division, print_function

which differs from the import in your error message.

@bwohlberg Apologies for the late reply. I tried to install sporoco with both pip and conda method. When I installed through pip, I ran into the same issue of Failed to build pyfftw, when I tried to install via conda.

I got an error message as follows:

(complex) youngwang@DF047 CAO_OCT % conda install -c conda-forge sporco
