现有TensorFlow MTCNN模型，转换过程中遇到一些问题，请求帮助：

模型repo: https://github.com/blaueck/tf-mtcnn

RKNN版本：1.0.0

转换系统：Ubuntu 18.04

代码：

  1. import numpy as np
  2. import cv2
  3. from rknn.api import RKNN

  5. rknn = RKNN()

  7. print('--> config model:')
  8. rknn.config(channel_mean_value='127.5 127.5 127.5 128', reorder_channel='0 1 2')
  9. print('done!')

  11. print('--> Loading tensorflow model:')
  12. ret = rknn.load_tensorflow(
  13.     tf_pb = './mtcnn.pb',
  14.     inputs = ['input'],
  15.     outputs = ['landmarks','prob','box'],
  16.     input_size_list = [[498,310,3]]
  17. )
  18. if ret != 0:
  19.     print('Load tensorflow model failed!')
  20.     exit(ret)
  21. print('done')

  23. print('-->Building model:')
  24. ret = rknn.build(do_quantization=True, dataset='./dataset.txt')
  25. if ret != 0:
  26.     print('Build MTCNN failed!')
  27.     exit(ret)
  28. print('done!')

  30. print('-->Export RKNN model:')
  31. ret = rknn.export_rknn('./mtcnn.rknn')
  32. if ret != 0:
  33.     print('Export mtcnn.rknn failed!')
  34.     exit(ret)
  35. print('done!')
复制代码

错误信息：

  1. --> config model:
  2. done!
  3. --> Loading tensorflow model:
  4. done
  5. -->Building model:
  6. E Catch exception when building RKNN model!
  7. T Traceback (most recent call last):
  8. T   File "rknn/api/rknn_base.py", line 498, in rknn.api.rknn_base.RKNNBase.build
  9. T   File "rknn/api/rknn_base.py", line 1067, in rknn.api.rknn_base.RKNNBase._quantize
  10. T   File "rknn/base/RKNNlib/app/tensorzone/workspace.py", line 221, in rknn.base.RKNNlib.app.tensorzone.workspace.Workspace.load_net
  11. T   File "rknn/base/RKNNlib/app/tensorzone/graph.py", line 125, in rknn.base.RKNNlib.app.tensorzone.graph.Graph.get_input_shape
  12. T UnboundLocalError: local variable 'in_layer' referenced before assignment
  13. Build MTCNN failed!
复制代码

一些问题：

1. 参数inputs和outputs有没有什么问题？查看pb文件的inputs和outputs参数一般是怎样进行的？

2. 解决上面的转换问题的一般性思路是什么？

请把verbose=True打开，才能知道具体是什么原因。目前这LOG看不出什么。
PB文件的io名字可以通过Netron软件查看

好复杂，看不太懂，verbose信息的解读有什么相关资料吗？还有，input_size_list = [[498,310,3]]的值应当如何确定呢？我用的就是test_image.jpg文件的大小。

https://github.com/blaueck/tf-mtcnn/blob/master/caffe2tf.py
tf-mtcnn 图像输入尺寸是
img_shape = [None, None, 3]

实际大小通过 tf.shape() 得到
def stage_one(images, min_size, factor, thresold, scope):
    img_shape = tf.shape(images)

rknn 输入必须规定图像尺寸， 但是模型没有提供， 可能是这个问题。
