Bugs in Cython wrapper

[Y Simson]

1) In debug mode all the locals generated by cython wrapper are printed. This makes debugging much harder than it aught to be

2)

from gtsam import Point3
Point3().vector()

throws an error:

  File "gtsam/gtsam.pyx", line 921, in gtsam.gtsam.Point3.vector (gtsam.cpp:33814)
    return ndarray_copy(ret).squeeze()
  File "eigency/conversions.pyx", line 28, in eigency.conversions.ndarray_copy_double_F (eigency/conversions.cpp:2958)
    cdef int itemsize = np.dtype(dtype).itemsize
TypeError: data type "double" not understood

Thanks for the report! I'm aware of the first problem. Haven't got time to fix it yet.

I can't reproduce the second bug. Which versions of cython, numpy and eigency are you using?

[Y Simson]

Thanks for that fast response.

I guess I can use a logger with outputs to text file to work around the first problem.

The second problem was caused by an error on my part. I switched python virtual environments but forgot to update the eigency installs in that environment.

[Duy-Nguyen Ta]

Ah great! I'm working on a way to avoid the Eigency installation issue. I'll look into the first problem after finishing that. Thanks!

In debug mode all the locals generated by cython wrapper are printed is a known issue. The second problem was my own error.
