Check the annotation. There may be some annotated boxes without class name "Person008" which does not match the parameter _object_names_array_ in _setTrainConfig()_

First of all, make sure to be running the last version of ImageAI, otherwise upgrade it.

No training samples were read. Check if every thing is correctly set up (the path to the folders with images/annotations). Also consider double checking the annotation files.

Please, update your status on this, or close it otherwise.

I also checked my xml file. But it shows correctly. I am having latest version of imageai also. Please help me out to solve my problem.

you might have added names to your object_names_array that you didn't annotate

[VijayaLakshmiArthanari]

My issue was solved with this, I placed the wrong object array name.
Also, The imageAI functions are quite outdated as I keep getting a depreciated warning while running my programs. Does anyone know when it'll be updated!

I am also getting this error, but in my case, everything works fine when I put all files in the train folder. the error comes as soon as I move some files to the validation folder. same files if put to the train folder works fine. I am using latest version of imageai. does anyone has faced this problem?
