ValueError: Tried to convert 'shape' to a tensor and failed. Error: None values not supported.

[Ishan-10038]

Dear Author, When I am running this part of the code inside Google Colab,

Creating model in Inference mode import tensorflow as tf with tf.device(DEVICE): model = modellib.MaskRCNN(mode="inference", model_dir=MODEL_DIR, config=config)

Loading the last best model which is trained weights_path = model.find_last()[1] custom_WEIGHTS_PATH = '/content/drive/MyDrive/car-damage-detection-using-CNN/logs/mask_rcnn_coco.h5'

Load weights print("Loading weights ", custom_WEIGHTS_PATH) model.load_weights(custom_WEIGHTS_PATH, by_name=True)

I get the following error: ValueError: None values not supported.

During handling of the above exception, another exception occurred:

ValueError Traceback (most recent call last) ValueError: None values not supported.

During handling of the above exception, another exception occurred:
