After uploading and submitting the csv, a popup showed Calculating… for some time. After that it showed Errored. Does that mean my submission was wrong? Or was there some problem while calculating?
Error message is displayed after submitting csv
Hey @SanchitSayala, make sure that you converted csv file in right format. First you need to reshape your image, to (-1,3) shape and than make csv.
img = img.reshape((-1,3))
import pandas as pd
pd.DataFrame(img).to_csv(“mysubmission.csv”, index = False, header = [‘r’,‘g’,‘b’])
Hope this resolved your doubt.
Plz mark the doubt as resolved in my doubts section. 
That did the job, thanks.
