Any ideas what this could be? Trying to upload a test data to test the model.

Hello @Nhuc Dang - Feeney Brothers
Thanks for reaching out to us for this issue. What does your data set look like? I have seen similar issue for pd.dataframe for your reference, please share more details so that we can look deeper.

Hi @YutongTie-MSFT ,
Dataset includes 787 columns x 2000 rows, consisting of image/decimal data. Column 787 is the label with either 1 or 0, the rest are all features consisting of column 785-786 are int numbers and Column from 1 to 784 are decimal.
The training is fine but when I upload a test set which consist of 786 (without the label column), the Azure ML throws that error.
Thanks

Update about this case:
During the support session, support team confirmed that PG has identified a bug where the target column in test data, which ideally should be optional, is currently required. PG will roll out the fix in the next python SDK release.
Sorry for the experience.
