Hi NuttyCamel41 !

Your suspicion is correct, there should be no need to specify the config.pbtxt manually, normally this file is made automatically using the information you provide using the command line.

It might be somehow silently failing to parse your CLI input to correctly build the config.pbtxt . One difference I see immediately is that you opted for "[1, 64]" notation instead of the 1 64 notation from the example. Might be worth a try to change the input format? Also please look carefully for any ClearML warnings or error logs when running the CLI command
