Python 输入与 input_signature 不兼容是什么意思
What does mean Python inputs incompatible with input_signature
我遇到了问题
ValueError: Python inputs incompatible with input_signature:
当我这样做时:
image_np = np.asarray(np.array(Image.open(image_path)))
input_tensor = tf.convert_to_tensor(image_np)
input_tensor = input_tensor[tf.newaxis, ...]
detections = detect_fn(input_tensor)
问题恰恰发生在这一行:
detections = detect_fn(input_tensor)
我做错了什么?这个错误是什么意思?
