There is no model header or source file in the outputs/ folder.
The archive contains logs only, and no footprint numbers are produced.
The reason is reported at the end of the log as an error code and message — for example, an unsupported operator or a layer dimension or reshape mismatch the compiler could not resolve.
Check the tail of the log for ERROR: lines to identify what needs to change in your model before re-exporting and re-uploading.
