When starting the processing of the satellite data, we start out with sz=64 and get the data. Then on the next line the data is resized and stored in the tmp directory:
data = data.resize(int(sz*1.3), 'tmp')
My question is why is this done? Is it not possible to set sz to 83 in the first place? For the other sz values that follow (128 & 256) no additional resizing is done.
I also noticed that this line changed where the models are saved. They are now in 'data/planet/tmp/83/models'. I found out by looking at learn.models_path.
UPDATE
OK, so this question is answered in the next lesson. So next time I have a question, I’ll put it on hold until I’ve watched the next video. Jeremy also answers here: Planet Classification Challenge
