Error: all the input array dimensions except for the concatenation axis must match exactly

Question

output=np.column_stack((
L1.values.ravel(),
L2.values.ravel(),
L3.values.ravel(),
L8.values.ravel(),
L9.values.ravel(),
L10.values.ravel(),
L11.values.ravel(),
WCSFC,
WCUPPER,
TCSFC,
DCSFC,
TCUPPER,
Tornado,
L1.latlons()[0].ravel(),
L1.latlons()[1].ravel()))

output = np.concatenate(map(pointInBox, output), output, axis=1)


np.savetxt(f, output, fmt="%f", delimiter=',')
f.close()

Returned:

return _nx.concatenate(arrays, 1)
ValueError: all the input array   dimensions except for the concatenation axis must match exactly

Answer 1

You are stacking 1D arrays as columns to make a 2D array. So, all of the arrays passed to concatenate must have shape (n, ), where the value of n must be the same for all your arguments. Clearly, in your case this does not happen. Find which argument(s) doesn't fit and remove it.
