_linear() got an unexpected keyword argument 'bias_start'

Excuse me, I got a TypeError:_linear() got an unexpected keyword argument 'bias_start' please help me ~

I meet the same problem when I try to use tensorflow==1.3.0. The problem is saved when I change it to the version guided. Good luck!

Unfortunately, this repo only supports tf 0.11 which had another definition of _linear. It's location and definition has since changed. I tried a lot to port it to 1.3 but to no avail. Did you find any solution? @st474ddr @WangJiuniu

@aneesh-joshi , maybe you can give my branch Tf1.8 a try, I was able to run it last month.

Hey @Vimos Thanks for replying. I ran your repo. However, I get the following error:

Traceback (most recent call last):

ImportError: cannot import name '_linear'

It's the same problem I faced while porting. I couldn't find any replacement for the _linear function. Even the old copied definition of _linear doesn't seem to solve it.

But you were able to run it. Am I missing something?

[Vimos]

@aneesh-joshi , try the tf1.8 branch, not the master branch.

[aneesh-joshi]

@Vimos Thanks a lot! (Like you said, I forgot to change branches) It's working.

Maybe you could make a PR to the original repo. It will be useful for everybody. Also, did you make any ChangeLog with the changes (any functionality you had to give up on for the newer version). I am reading the diff, but a shorted log would be easier.

[Vimos]

@aneesh-joshi Glad that it's helping! The official repo has a dev branch which contains modifications to be compatible with >Tf1.0. Although I pulled their code, there are still some conflicts among different versions of TF. Since the repo is not actively maintained, I am not quite sure which branch to make the PR.

In nn.py: replace from tensorflow.python.ops.rnn_cell_impl import _linear with from tensorflow.contrib.rnn.python.ops.core_rnn_cell import _linear

replace flat_out = _linear(flat_args, output_size, bias, bias_start=bias_start, scope=scope with with tf.variable_scope(scope or 'Linear'): flat_out = _linear(flat_args, output_size, bias, bias_initializer=tf.constant_initializer(bias_start))

You can refer to the code to read the _linear() function.
