尝试转换此模型时，为什么会出现语法错误？

Question

这是TensorFlow文档提供的用于将tf2模型转换为tflite的脚本：https://www.tensorflow.org/lite/convert#cmdline

我只将路径添加到了SavedModel目录。

import tensorflow as tf

# Convert the model
converter = tf.lite.TFLiteConverter.from_saved_model('./exported-models/my_model/saved_model') # path to the SavedModel directory
tflite_model = converter.convert().

# Save the model.
with open('model.tflite', 'wb') as f:
  f.write(tflite_model)

我在tflite_model = converter.convert（）时遇到错误。我应该添加一些东西吗？如果我删除点（。），那么我会遇到以下错误：

During handling of the above exception, another exception occurred:
