Hi, I just noticed that my inference submission failed. Looking at the logs, it is getting out of bound for indexing for the 6th element of the image crosswalk which seems unavailable. It corresponds to the image_filename for the training set. I never found any documentation that the format for the image crosswalk on the test set is different from the training set. Could you please point to the relevant documentation?

Hi Hossein, > That's my guess too, I just don't understand why the examIndex is not there and am unable to find any documentation regarding that. Please refer to the [Challenge Dictionary](https://www.synapse.org/#!Synapse:syn7214004) to know what the columns of each file are (see Section "Images crosswalk" from the page [Data Description](https://www.synapse.org/#!Synapse:syn4224222/wiki/401750)).
Hi Thomas, Thanks for the reply. Honestly, I am still unable to find any indication of that in neither the documentation of the Pilot Data nor the Cheat Sheet. In fact, the tf basic model provided as part of the challenge accesses the columns by indexing and not their names. In any case I am unable to resubmit as the deadline have passed and I am almost sure, as Bill suggested, that the examIndex is absent from the inference metadata for some reason which is really unfortunate. I wonder if it is possible to run the main inference submissions against a metadata file with the examIndex so that it does not fail. Bill: That's my guess too, I just don't understand why the examIndex is not there and am unable to find any documentation regarding that.
Is your problem specifically for Sub-challenge 1? I ran into this issue as well because I accidentally tried to get the 'examIndex', which isn't there for Sub-challenge 1, so you may just need to account for that as well.
Hi Hossein, > it is getting out of bound for indexing for the 6th element of the image crosswalk Please refer to the [documentation of the Pilot Data](https://www.synapse.org/#!Synapse:syn6174174) and let me know if it solves your issue. Also, we recommend in the [Cheat Sheet](https://www.synapse.org/#!Synapse:syn4224222/wiki/409763) to refer to the columns of a table by their name. Thanks!

One column is missing from the image crosswalk in the test set page is loading…
