Model fails to save after training #21

Open BWWS opened 2 years ago

Hi,

I am seeing the following error:

Training is finished! Exporting model... Traceback (most recent call last): File "C:\TensorFlowObjectDetection\TFODCourse\Scaled_YOLOv4_tf2\train.py", line 382, in main(args) File "C:\TensorFlowObjectDetection\TFODCourse\Scaled_YOLOv4_tf2\train.py", line 374, in main model = Yolov4(args, training=False) File "C:\TensorFlowObjectDetection\TFODCourse\Scaled_YOLOv4_tf2\model\yolov4.py", line 11, in Yolov4 scaled_yolov4_csp_darknet53_outputs = scaled_yolov4_csp_darknet53(input,mode=args.model_type) File "C:\TensorFlowObjectDetection\TFODCourse\Scaled_YOLOv4_tf2\model\CSPDarknet53.py", line 35, in scaled_yolov4_csp_darknet53 x = conv2d_bn_mish(x, 32, (3, 3), name="first_block") File "C:\TensorFlowObjectDetection\TFODCourse\Scaled_YOLOv4_tf2\model\common.py", line 7, in conv2d_bn_mish return x tf.math.tanh(tf.math.softplus(x)) File "C:\TensorFlowObjectDetection\TFODCourse\tfod\lib\site-packages\tensorflow\python\util\traceback_utils.py", line 153, in error_handler raise e.with_traceback(filtered_tb) from None File "C:\TensorFlowObjectDetection\TFODCourse\tfod\lib\site-packages\keras\layers\core\tf_op_layer.py", line 119, in handle return TFOpLambda(op)(args, **kwargs) File "C:\TensorFlowObjectDetection\TFODCourse\tfod\lib\site-packages\keras\utils\traceback_utils.py", line 70, in error_handler raise e.with_traceback(filtered_tb) from None OverflowError: Exception encountered when calling layer "tf.math.softplus" (type TFOpLambda).

Python int too large to convert to C long

Call arguments received by layer "tf.math.softplus" (type TFOpLambda): • features=tf.Tensor(shape=(None, None, None, 32), dtype=float32) • name=None

I still have the checkpoints saved and a temp_model_variables.h5 has been created but I am unable to convert these into a saved model.

Any advice?
