我正在对 frozon .pb 模型文件运行 OpenVINO 优化。运行优化时，它显示以下错误消息：

model.summary() 的输出

我正在运行优化如下。
input_shape = [0, 10, 50]
input_shape_str = str(input_shape).replace(' ','')
input_shape_str
!python3 {mo_tf_path} --input_model {pb_file} --output_dir {output_dir} --input_shape {input_shape_str} --data_type FP32
这里有什么问题？
