ValueError: broadcast from shape (10,1) into shape (10)

[alexvoronov]

Hi, I'm getting the following error when running either prob2socp or prob_to_socp on generated python code:

ValueError: could not broadcast input array from shape (10,1) into shape (10)

The minimal example where I get this error is here:

#!/usr/bin/env python
from qcml import QCML

if __name__ == '__main__':

    s = """variable x(10)
    minimize sum(2 * x)"""

    p = QCML()
    p.parse(s)
    p.canonicalize()
    p.codegen("python")
    socp_data = p.prob2socp(params=locals())

Ah, thanks. I have the wrong "type" for numpy: They distinguish between arrays of size (10,1) and arrays of size (10,).
