Python 如何加载和运行TensorFlow模型

超级简单的问题

我将遵循本教程：

我已经按照说明（不是可选部分）训练了一个模型，并使用tf.saved\u model.save保存了它

现在，我想运行一个新的图片模型。我该怎么做

我尝试了以下方法：

loaded = tf.saved_model.load("/tmp/saved_flowers_model")
print(list(loaded.signatures.keys()))  # ["serving_default"]

infer = loaded.signatures["serving_default"]
print(infer.structured_outputs)

file = .../pic.jpg
output = loaded (file)

返回了以下错误：

ValueError: Could not find matching function to call loaded from the SavedModel. Got:
  Positional arguments (3 total):
    * /Users/dansafdie/Documents/Code Repos/Image Classifier/flower_photos/daisy/19834392829_7d697871f6.jpg
    * False
    * None
  Keyword arguments: {}

Expected these arguments to match one of the following 4 option(s):

Option 1:
  Positional arguments (3 total):
    * TensorSpec(shape=(None, 224, 224, 3), dtype=tf.float32, name='inputs')
    * True
    * None
  Keyword arguments: {}

Option 2:
  Positional arguments (3 total):
    * TensorSpec(shape=(None, 224, 224, 3), dtype=tf.float32, name='inputs')
    * False
    * None
  Keyword arguments: {}

Option 3:
  Positional arguments (3 total):
    * TensorSpec(shape=(None, 224, 224, 3), dtype=tf.float32, name='input_1')
    * False
    * None
  Keyword arguments: {}

Option 4:
  Positional arguments (3 total):
    * TensorSpec(shape=(None, 224, 224, 3), dtype=tf.float32, name='input_1')
    * True
    * None
  Keyword arguments: {}
