模型转化时，量化未开启时，可以转成功，量化开启开启时。报错如下：

Build model failed!

运行代买如下

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

if __name__ == '__main__':

# Create RKNN object
rknn = RKNN(verbose=True)
rknn.config(channel_mean_value='0 0 0 1', reorder_channel='0 1 2',batch_size = 1)
print('done')

# Load tensorflow model
ret = rknn.load_onnx(model = './model_embding_gpu_1.1.0.onnx')
if ret != 0:
      print('Load model failed!')
      exit(ret)
print('done')

# Build model
print('--> Building model')

#ret = rknn.build(do_quantization=False)
ret = rknn.build(do_quantization=True, dataset='./dataset.txt')
if ret != 0:
      print('Build model failed!')
      exit(ret)
print('done')
# Export rknn model
print('--> Export RKNN model')
ret = rknn.export_rknn('./person_reid_quantization.rknn')
if ret != 0:
      print('Export model failed!')
      exit(ret)
print('done')

rknn.release()
