I have a getX() which gives a 2D array(shape=(18,2)) as an output for each frame of an image. I want to add this continuously updating array to the csv. I have used the following code. But it is giving me only one row(probably for only one frame).
with open("data.csv",mode ='w') as csvfile: wr = csv.writer(csvfile, quoting = csv.QUOTE_ALL,dialect="excel") get_val = oneObject.getX(currentFrameIndex) for currentFrameIndex in get_val: wr.writerow(humanPos)
Why not accumulate your sub-arrays and then use
np.savetxt to write to CSV just once?
arrs =  for currentFrameIndex in listOfFrameIndices: # Demonstrative only. arrs.append(oneObject.getX(currentFrameIndex)) # Or, # arrs = np.array([oneObject.getX(c) for c in listOfFrameIndices]) np.savetxt('file.csv', np.array(arrs), delimiter=',')
