Description
I am working with Arduino_TensorFlowLite-2.4.0-ALPHA-precompiled library and trying to compile my arduino sketch. But I keep getting this error `Library Arduino_TensorFlowLite has been declared precompiled:

I've included my sketch below. Any help would be greatly helpful. Thanks

Commencez par la sortie de l'éditeur de liens pour Arduino_TensorFlowLite-2.4.0-ALPHA-precompiled et les lignes 35–36 référencées de tensorflow/lite/micro/micro_error_reporter.cpp. Examinez le sketch inclus, en particulier sa configuration de MicroErrorReporter, et déterminez ce qui provoque l'absence du symbole DebugLog. La tâche est terminée lorsque le sketch se compile sans erreurs undefined-reference.
