1 year ago Parece estar relacionado con el modo "eager" de Keras. ¿puedes probar a deshabilitarlo al principio de todo? Es distinto según la versión de Tensorflow/Keras que uses. En este enlace de StackOverflow comentan diversas formas de hacerlo: https://stackoverflow.com/questions/53429896/how-do-i-disable-tensorflows-eager-execution

Para poder usar el código he tenido que adaptar la función "leer_annotations" para que en vez de xml leyera el json de cada imagen.
