BB,
In a numpy array of m x n size, I would like to delete few rows when a given element in that row is 'nan' or say any other value.
For e.g. as in example given below, if I wish to delete a row when the 3rd element of row is zero, or if 3rd, 4th, 5th element are zero or either of 3rd, 4th and 5th element is zero.
array([[ 1900. , nan, nan, nan, nan, nan],
[ 1900.5, nan, nan, nan, nan, nan],
[ 1901. , nan, nan, nan, nan, nan],
...,
[ 6724. , nan, nan, nan, nan, nan],
[ 6724.5, nan, nan, nan, nan, nan],
[ 6725. , nan, nan, nan, nan, nan]])
Cheers
Sachin
