File not found error

I have created all the folders as mentioned but still getting this error

Hi, it seems that you are missing some directories. The '0001_NI000_slice000.npy' file is an output file(nodule image). Thus, it is a file that is being made when you run the code. Check if you have made the \data\Image directory or have made the needed changes in the config_file_create.py file

please let me know if you have solved it

I have made the data/Image directory. The problem I am facing is the program is creating two directories with the name of LIDC-IDRI-0001 in the data/Image folder. So it is not not able to find the path.
I am getting this 'D:\data\Mask\LIDC-IDRI-0001\LIDC-IDRI-0001\0001_MA000_slice000.npy' but it should be
'D:\data\Mask\LIDC-IDRI-0001\0001_MA000_slice000.npy'
I have resolved the issue.

I will go through the codes again! thanks for letting me know

[Rukhmini]

You just need to change the lines to
patient_image_dir = IMAGE_DIR #IMAGE_DIR / pid
patient_mask_dir = MASK_DIR

[jaeho3690]

solved this issue by changing

nodule_name = "{}_NI{}_slice{}".format(pid[-4:],prefix[nodule_idx],prefix[nodule_slice])
mask_name = "{}_MA{}_slice{}".format(pid[-4:],prefix[nodule_idx],prefix[nodule_slice])
