All false Mask (= m1+m2) in preprocessing for some scans from stage2 #74

Hi, it might be the threshold problem, i.e. the volume of the lung if
smaller than the threshold. But I am not sure, I suggest you to debug the
step_python1 function line by line, the ideas of the function is discribed
in our paper, and we discribed the output of each module, you should see
similar results in those normal cases.

… Hello everybody,
Since 2 days, I am trying to run main.py to see if everything is working
correctly. Unfortunately, I am running into problems during the
preprocessing for some files, e.g. ac7493533e667b077b7180642fb1dc4d
The problem is that in line 70 of full_prep.py:
im, m1, m2, spacing = step1_python(os.path.join(data_path,name))
All elements in m1 and m2 are False. Which results in empty arrays for
xx,yy,zz in line 74:
xx,yy,zz= np.where(Mask)
Afterwards the code fails since there is no np.min() for empty arrays.
First I thought maybe the file got corrupted during download so I
downloaded stage2 again, but that didn't help.
I don't use the right versions for some of the python modules, e.g. numpy
1.11.13 doesn't work (mkl problems - still investigating) therefore I am
using 1.12, I have hard times to believe that this is causing problems
since the preprocessing is working for most of the files.
Has anybody an idea what else I could try? Thanks in advance!

Hello, I'd like to ask how to download stage2 data，Thanks |
|
Thanks for replying! I used the kaggle api twice and did one direct
download (from the kaggle page).
Right now I am running the preprocessing on the training set (stage1) and
so far it seems fine - it did 200 examples without a problem. So maybe in
the end my stage 2 data is corrupted.
Any other ideas?

In the end it seems like my environment was causing the preprocessing to fail. Finally, I got it to work. Here is my conda environment: name: nodules
