@skaak thanks for the respond but iam steal getting this error while summitting

sample_index = gt_df['sample_index']

submission_df = pd.DataFrame(adjusted_test_preds, columns=['P', 'K', 'Mg', 'pH'])

submission_df['sample_index'] = sample_index

submission_tall = submission_df.melt(id_vars='sample_index',

value_vars=['P', 'K', 'Mg', 'pH'],

var_name='Parameter',

value_name='Target')

submission_tall['sample_index'] = submission_tall['sample_index'].astype(str)

submission_tall['sample_index'] = submission_tall['sample_index'] + '_' + submission_tall['Parameter']

submission_tall = submission_tall[['sample_index', 'Target']]

submission_tall.to_csv('submission_Tall.csv', index=False)

Any assistance in resolving this issue would be greatly appreciated.

Not sure - your code looks fine, but I did not run it.

I note my 'Target' is named '0', perhaps try to rename 'Target' to 0 and try again. I can't remember, but I think I must have gotten this from the starter notebook, but if it does not work, paste in the head of your submission here to inspect.

Here is my code fwiw

tall_sub = []

for i in [ "P", "K", "Mg", "pH" ] :

	tall_sub.append ( pd.DataFrame ( baseline_sub [ i ].values, index = baseline_sub.index.to_series ().apply ( lambda x : str ( x ) + "_" + i ) ) )

tall_sub = pd.concat ( tall_sub, axis = 0 )
tall_sub.to_csv ( "sub.csv", index_label = "sample_index" )

Thanks @skaak it works

Thanks, I see you are making real good progress. All the best, you have a strong model from the start.

thanks @skaak can i have ur email address

Ok - remember we can not discuss this competition in any significant detail offline, unless we are a team, as that is against the rules.
