error running code

[ashishkr23]

i followed all the steps but get the following error.

File "/home/ashishkr/projects/python/transformer/modules.py", line 227, in multihead_attention
tril = tf.contrib.linalg.LinearOperatorTriL(diag_vals).to_dense() # (T_q, T_k)
AttributeError: 'module' object has no attribute 'LinearOperatorTriL'

tf version 1.5.0 and 1.7.0
would be great if you can point out a solution

function has been changed to LinearOperatorLowerTriangular

Thank you! I have the same problem and it works for me!

-  tril = tf.contrib.linalg.LinearOperatorTriL(diag_vals).to_dense() # (T_q, T_k)
+  tril = tf.linalg.LinearOperatorLowerTriangular(diag_vals).to_dense() # (T_q, T_k)

Hi, bro, how do you deal with such VERSION problems? I think google should add some instructions in the history versions.

Hello I am getting a similar error.
File "/Users/aishwarya/Desktop/transformers/modules.py", line 227, in multihead_attention
tril = tf.contrib.linalg.LinearOperatorLowerTriangular(diag_vals).to_dense() # (T_q, T_k)
AttributeError: module 'tensorflow.contrib' has no attribute 'linalg'

My tf version is - 1.13.0-dev20181108
Any guidance will be really helpful.

I think you should exclude 'contrib' when you use this function.
In my case, it works well (tf version 1.12.0)
