can you offer the test demon script?

[Lvhhhh]

i have trained the network and get the model. but i dont know how to visualize the result? i obtain the csv_results.csv and folder(train and valid).

You can use the tensorboard. Point it to the directory where you save the models. There should be summaries there.

maybe i do not make it clear. if i have the test video. how to show the result using the model i trained

[Lvhhhh]

now you have just offer the train code . can you offer the test code for the other test video ? i want to see the result of the code

@Lvhhhh Use this script to load the model, and run it on new datasets:

            with tf.Session() as sess:
    
                    meta_graph_def = tf.saved_model.loader.load(
                                           sess,
                                           [tf.saved_model.tag_constants.SERVING],
                                           path_to_model
                                       )
                    print('\n')
        
                    signature = meta_graph_def.signature_def
                    signature_key = 'prediction'  #tf.saved_model.signature_constants.DEFAULT_SERVING_SIGNATURE_DEF_KEY
                    input_key = 'images'
                    training_flag_key = 'is_training'
                    output_key = 'sigmoid'
        
                    x_tensor_name = signature[signature_key].inputs[input_key].name
                    print('x_tensor_name', x_tensor_name)
        
                    training_flag_tensor_name = signature[signature_key].inputs[training_flag_key].name
                    print('training_flag_tensor_name', training_flag_tensor_name)

                    tflag_op = sess.graph.get_tensor_by_name(training_flag_tensor_name)
        
                    y_op = sess.graph.get_tensor_by_name(y_tensor_name)
        
                    x = cv2.imread(__full_path_wExt_img_fn__, cv2.IMREAD_UNCHANGED)
        
                    #[height, width]
                    print(x.shape)
        
                    if len(x.shape) != 2:

                    input_list = []
        
                    input_list.append(y)
        
                    input_list = np.asarray(input_list).astype(np.float32)
        
                    print(input_list.shape)
