.pb文件转换为tflite文件遇到问题汇总_toco failed. see console for info.

1、AttributeError: type object 'TFLiteConverterV2' has no attribute 'from_frozen_graph'    或者 convertr = tf.lite.TFLiteConverter.from_frozen_graph(in_path, input_arrays=input_tensor_name   AttributeError: module 'tensorflow' has no attribute 'lite'

对于tenorflow版本不对，利用aconda新建一个环境，安装：tensorflow 1.13.1(亲测，有效)

conda install tensorflow=1.13.1
或则：
pip install tensorflow==1.13.1

2、tensorflow.lite.python.convert.ConverterError: TOCO failed. See console for info.

以及后面还跟了一长串：

这个问题困扰了我很久，换了很多版本，我都不能跑通，最后在代码里面加了：

converter.post_training_quantize = True

问题解决！

最后自己转换成功代码为：

import tensorflow as tf
 
# 把pb文件路径改成自己的pb文件路径即可
path="E:/LX/tensorflow/yolov3_coco_v3.pb"        #pb文件位置和文件名
 
# 如果是不知道自己的模型的输入输出节点，建议用tensorboard做可视化查看计算图，计算图里有输入输出的节点名称
inputs=["input/input_data"]
#模型文件的输入节点名称
outputs=["pred_sbbox/concat_2", "pred_mbbox/concat_2", "pred_lbbox/concat_2",
                         "pred_multi_scale/concat"]            #模型文件的输出节点名称
 
input_tensor = {inputs[0]:[1,416,416,3]}
# 转换pb模型到tflite模型
converter = tf.lite.TFLiteConverter.from_frozen_graph(path, inputs, outputs,input_tensor)
converter.post_training_quantize = True
converter.allow_custom_ops=True
tflite_model = converter.convert()
# model_tflite.tflite这里改成自己想要保存tflite模型的地址即可
open("E:/LX/tensorflow/model_tflite.tflite", "wb").write(tflite_model)

3 出现一下提示，不是错误，但是让人看着烦：

numpy版本不对，重装numpy版本！

pip uninstall numpy
pip install numpy==1.16.4

最后稍微提一下，网络上：pb文件转tflite文件代码汇总：

1

import tensorflow as tf
 
# 把pb文件路径改成自己的pb文件路径即可
path="E:/LX/tensorflow/yolov3_coco_v3.pb"        #pb文件位置和文件名
 
# 如果是不知道自己的模型的输入输出节点，建议用tensorboard做可视化查看计算图，计算图里有输入输出的节点名称
inputs=["input/input_data"]
#模型文件的输入节点名称
outputs=["pred_sbbox/concat_2", "pred_mbbox/concat_2", "pred_lbbox/concat_2",
                         "pred_multi_scale/concat"]            #模型文件的输出节点名称
 
input_tensor = {inputs[0]:[1,416,416,3]}
# 转换pb模型到tflite模型
converter = tf.lite.TFLiteConverter.from_frozen_graph(path, inputs, outputs,input_tensor)
converter.post_training_quantize = True
converter.allow_custom_ops=True
tflite_model = converter.convert()
# model_tflite.tflite这里改成自己想要保存tflite模型的地址即可
open("E:/LX/tensorflow/model_tflite.tflite", "wb").write(tflite_model)

2、

import tensorflow as tf
import os
os.environ["CUDA_VISIBLE_DEVICES"] = "0"
config = tf.ConfigProto()
config.gpu_options.allow_growth = True
 
graph_def_file = "E:/LX/tensorflow/yolov3_coco_v3.pb"
 
input_names = ["input/input_data"]
output_names = ["pred_sbbox/concat_2", "pred_mbbox/concat_2", "pred_lbbox/concat_2",
                         "pred_multi_scale/concat"]
input_tensor = {input_names[0]:[1,416,416,3]}
 
 
#uint8 quant
converter = tf.lite.TFLiteConverter.from_frozen_graph(graph_def_file, input_names, output_names, input_tensor)
converter.target_ops = [tf.lite.OpsSet.TFLITE_BUILTINS,tf.lite.OpsSet.SELECT_TF_OPS]
converter.allow_custom_ops=True
 
converter.inference_type = tf.uint8    #tf.lite.constants.QUANTIZED_UINT8
input_arrays = converter.get_input_arrays()
converter.quantized_input_stats = {input_arrays[0]: (127.5, 127.5)} # mean, std_dev
converter.default_ranges_stats = (0, 255)
 
tflite_uint8_model = converter.convert()
open("uint8.tflite", "wb").write(tflite_uint8_model)

3、

import tensorflow as tf
 
in_path = r'E:/LX/tensorflow/yolov3_coco_v3.pb'
out_path = r'E:/LX/tensorflow\output_graph.tflite'
 
input_tensor_name = ['input/input_data']
input_tensor_shape = {'input/input_data': [1, 416, 416, 3]}
 
class_tensor_name = ["pred_sbbox/concat_2", "pred_mbbox/concat_2", "pred_lbbox/concat_2",
                          "pred_multi_scale/concat"]
 
convertr = tf.lite.TFLiteConverter.from_frozen_graph(in_path, input_arrays=input_tensor_name
                                                     , output_arrays=class_tensor_name
                                                     , input_shapes=input_tensor_shape)
 
# convertr=tf.lite.TFLiteConverter.from_saved_model(saved_model_dir=in_path,input_arrays=[input_tensor_name],output_arrays=[class_tensor_name])
tflite_model = convertr.convert()
 
with open(out_path, 'wb') as f:
    f.write(tflite_model)

.h转换为tflite:

import tensorflow as tf
tf.compat.v1.disable_eager_execution()
converter =  tf.compat.v1.lite.TFLiteConverter.from_keras_model_file('F:\yolo\yolo.h5')
tflite_model = converter.convert()
open("yolov3.tflite", "wb").write(tflite_model)
