numpy sort is not working
Hi everyone, I have a numpy array of dimensions
allRics.shape (583760, 1)
To sort the array, I set the dtype of the array as follows: allRics.dtype = [('idx', np.float), ('opened', np.float), ('time', np.float),('trdp1',np.float),('trdp0',np.float),('dt',np.float),('value' ,np.float)]
allRics.dtype
dtype([('idx', ' x=np.sort(allRics,order='time') x[17330:17350]['time'] array([[ 61184.4 ],
[ 61188.51 ],
[ 61188.979],
[ 61188.979],
[ 61189.989],
[ 61191.66 ],
[ 61194.35 ],
[ 61194.35 ],
[ 61198.79 ],
[ 61198.145],
[ 36126.217],
[ 36126.217],
[ 36126.218],
[ 36126.218],
[ 36126.219],
[ 36126.271],
[ 36126.271],
[ 36126.271],
[ 36126.293],
[ 36126.293]])
Time column doesn't change its order. Could someone please advise what
is missing here? Is this related to the bug
