I am trying to add zeros to certain variables in order to make them all the same length (100,) and put them in a masked table.
It works fine when concatenate zeros to my variable propNum
that is a single number but creates a (2,) length array when I try it with my variable time_04_window
that has 62 values.
Code that works:
propNum = 100
table_propNum = np.concatenate([[propNum], np.zeros(len(x)-1, dtype=float)])
Code that is not working:
time_04_window = [ 20029625.91881907 20029626.91881907 20029627.91881907 20029628.91881907 20029629.91881907 20029630.91881907 20029631.91881907 20029632.91881907 20029633.91881907 20029634.91881907 20029635.91881907 20029636.91881907 20029637.91881907 20029638.91881907 20029639.91881907 20029640.91881907 20029641.91881907 20029642.91881907 20029643.91881907 20029644.91881907 20029645.91881907 20029646.91881907 20029647.91881907 20029648.91881907 20029649.91881907 20029650.91881907 20029651.91881907 20029652.91881907 20029653.91881907 20029654.91881907 20029655.91881907 20029656.91881907 20029657.91881907 20029658.91881907 20029659.91881907 20029660.91881907 20029661.91881907 20029662.91881907 20029663.91881907 20029664.91881907 20029665.91881907 20029666.91881907 20029667.91881907 20029668.91881907 20029669.91881907 20029670.91881907 20029671.91881907 20029672.91881907 20029673.91881907 20029674.91881907 20029675.91881907 20029676.91881907 20029677.91881907 20029678.91881907 20029679.91881907 20029680.91881907 20029681.91881907 20029682.91881907 20029683.91881907 20029684.91881907 20029685.91881907 20029686.91881907]
table_time_04_window = np.concatenate([[time_04_window], np.zeros(len(x)-len(time_04_window), dtype='i')])
len(x) = 100
So, time_04_window
is an array with length 62 and all floats, and I want to add 38 zeros to the array to give it a length of 100.
At first it was running for table_time_04_window
and now it is giving me
ValueError: all the input arrays must have same number of dimension
You should pass time_04_window
rather than [time_04_window]
, that's the dimension issue, ie
In [11]: table_time_04_window = np.concatenate([time_04_window, np.zeros(100-len(time_04_window), dtype='i')])
Note: Rather than concatenate you can also right pad with np.pad
:
In [21]: np.pad(np.array([1, 2, 3]), (0, 5), mode='constant')
Out[21]: array([1, 2, 3, 0, 0, 0, 0, 0])
