标题: 运行mobilenetssd-v2 无法转换 rknn 模型
系统：fedora28
toolkit版本： 1.0.0
tensorflow版本： 1.10.1

按照官方的训练步骤重新训练了pb文件
用mobilenetssd-v2 step1.py 无法转换
不知道什么原因谢谢指导~~~

step1.py 代码：

import numpy as np
import cv2
from rknn.api import RKNN

if __name__ == '__main__':

# Create RKNN object
rknn = RKNN(verbose = True, verbose_file =  './Error.log')

# pre-process config
print('--> config model')
rknn.config(channel_mean_value='127.5 127.5 127.5 128', reorder_channel='0 1 2', quantized_dtype='asymmetric_quantized-u8')
print('done')

# Load tflite model
print('--> Loading model')
ret = rknn.load_tensorflow(tf_pb='./frozen_inference_graph.pb',
                           inputs=['FeatureExtractor/MobilenetV2/MobilenetV2/input'],
                           outputs=['concat_1', 'concat'],
                           input_size_list=[[300,300,3]],
                           predef_file=None)
if ret != 0:
      print('Load model failed!')
      exit(ret)
print('done')

if ret != 0:
      print('Load model failed!')
      exit(ret)
print('done')

# Build model
print('--> hybrid_quantization_step1')
ret = rknn.hybrid_quantization_step1(dataset='./dataset.txt')
if ret != 0:
      print('hybrid_quantization_step1 failed!')
      exit(ret)
print('done')

# Tips
print('Please modify ssd_mobilenet_v2.quantization.cfg!')
print('==================================================================================================')
print('Modify method:')
print('1. delete @FeatureExtractor/MobilenetV2/expanded_conv/depthwise/depthwise_227:weight and its value')
print('2. delete @FeatureExtractor/MobilenetV2/expanded_conv/depthwise/depthwise_227:bias and its value')
print('3. delete @FeatureExtractor/MobilenetV2/Conv/Relu6_228

ut0 and its value')
print('==================================================================================================')
print('Original quantization profile and modified quantization profile diff shows in file quantization_profile.diff')

rknn.release()

是不是你的pb文件是高版本的TensorFlow生成的，上面日志，报错的点在TensorFlow里面。
