Error when using wass

[siyuanzhao]

Thanks for sharing your code and excellent work!

I try to run your code on other experimental data. However, I run into an error when using wass. The code works when other imb_funs (mmd2_rbf) are used.

Attached is the error log. Do you have any idea about what might cause this error so that I could fix it?

The reported issue might be because of a mismatch in the tf version. I used tf version=1.14 and the API seems to be broken. I fixed the code by making the following changes in the wasserstein() function:

col = tf.concat([delta*tf.ones(tf.shape(M[:,0:1])),tf.zeros((1,1))], axis=0)
Mt = tf.concat([M,row], axis=0)
Mt = tf.concat([Mt,col], axis=1)
a = tf.concat([p*tf.ones(tf.shape(tf.where(t>0)[:,0:1]))/nt, (1-p)*tf.ones((1,1))], axis=0)
b = tf.concat([(1-p)*tf.ones(tf.shape(tf.where(t<1)[:,0:1]))/nc, p*tf.ones((1,1))], axis=0)
