Hi, I am creating numpy arrays in chunks and I want to save the chunks while my program creates them. I tried to use numpy.save but it failed (because it is not intended to append data). I'd like to know what is, in your opinion, the best way to go. I will put a few thousands every time but building up a file of several Gbytes. I do not want to put into memory all previous data each time. Also I cannot wait until the program finishes, I must save partial results periodically. Thanks, any help will be appreciated Juan
