I also encountered the same mistake. How did you solve it?

[futureisatyourhand]

I solved this problem, /linear_cos/architecture.py is on line 87,
Converting"return tf.sqrt(tf.reduce_sum(filtfilt, [0, 1,2], keep_dims=True)+eps)"
  To "return tf.sqrt(tf.reduce_sum(filtfilt, [0, 1], keep_dims=True)+eps)"

p=filt.get_shape().as_list()
dim_s=list(range(len(p)-1))
return tf.sqrt(tf.reduce_sum(filt*filt,dim_s, keep_dims=True)+eps)
this will solve the problem

Hello, I modified the code according to your answer, but it still shows an error. Can you discuss it on email or WeChat with me? my mailbox is [email protected]. Thank you very much.
