Hi,
I have searched online and forum for a solution to no avail on this error on DL1 Lesson 3 Rossman:
joined_test[['Id','Sales']].to_csv(csv_fn, index=False)
FileNotFoundError: [Errno 2] No such file or directory: 'data\\rossmantmp/sub.csv'
I checked the directory data/rossman/tmp exist but no sub.csv file in it.
There is data/rossman/model/ with tmp.h5 and val0.h5 files.
Running latest jupyter (git pull and conda env update) on environment-cpu.yml on Win 8.1
Uploaded error:
