can't find "tf.nn.ctc_greedy_decoder" function #473

Closed geminird closed 4 years ago

geminird commented 4 years ago

Hello, In my project， need use the ”tf.nn.ctc_greedy_decoder” and "tf.sparse_tensor_to_dense" functions , how to do in tensorflow.net api.

and can I use the "Tensorflow.Operations.rnn.static_bidirectional_rnn" funciton instead of "tf.nn.bidirectional_dynamic_rnn" function?

use "tf.variance_scaling_initializer()" instead of "tf.contrib.layers.variance_scaling_initializer()"?

  1. Is your project open source? If not, please contact scisharpstack@gmail.com for support.
  2. I'm not sure, please refer tensorflow's manual.
  3. They are aliases and produce the same result. You can use tf.variance_scaling_initializer(). Please refer to this issue SciSharp/TensorFlow.NET#356.

@Oceania2018 open soruce python project at here https://github.com/jinxiwang/ocr_TDR，I'm try to use tensorflow.net implemet it. the method url at here https://github.com/jinxiwang/ocr_TDR/blob/master/test_crnn.py, line :32，another method https://github.com/jinxiwang/ocr_TDR/blob/master/crnn.py line 46,57,112。

@geminird I'm saying where is your .net version is? We'd like to help if your .net version is also open source.

geminird commented 4 years ago

@Oceania2018 The. Net version is just beginning. Because I started to learn tensorflow, as a learning sample, I can't rewrite program several problems, so I came to help. After the later program is sure to run, I will open it up on GitHub.

@Oceania2018 I pull it, see here :https://github.com/geminird/TfConsoleApp

@Oceania2018 网络不太好，没看到您的头像，您应该也是华人吧。这个是当作学习示例，目前改写了预测代码，程序跑不通。主要在CRNN类的74行，是参照BUG412修改的，但是还是不行，也把redis版本升级到1.15.0了，照样运行不了，不知道怎么解决，估计是那些匹配不到的函数替换错了。
