Training problem! about ac-gan HOT 4 OPEN

According to https://www.tensorflow.org/api_docs/python/tf/concat concatenation axis should be the second argument passed to tf,concat. so basically you need to fix lines 86 and 95 by switching the arguments.

Hi, I switched the arguments in lines 86 and 95
Line 86:
from: y_disc = tf.concat(0,[y, y * 0])
to: y_disc = tf.concat([y, y * 0], 0)

Line 95:
from: z = tf.concat(1, [z_cat.sg_one_hot(depth=cat_dim), z_con, z_rand])
to: z = tf.concat([z_cat.sg_one_hot(depth=cat_dim), z_con, z_rand], 1)

and this following error occurs:

Traceback (most recent call last):

ValueError: Tried to convert 'reduction_indices' to a tensor and failed. Error: Argument must be a dense tensor: range(0, 1) - got shape [1], but wanted [].

The complete fix to this problem is to switch the arguments on line 86 as mentioned above, and then replace line 95 with:

z = tf.concat(axis=1, values=[z_cat.sg_one_hot(depth=cat_dim), z_con, z_rand])

For some reason explicitly giving the arg names fixes it.

Hi, I met the same problem and solved it. The TensorFlow version mismatches SugarTensor here. You may try an earlier version of TensorFlow 1.7.
Also, you can modify the SugarTensor itself. Please go to sugartensor/sglogging.py, line 170 and line 176. You can delete the underscore before _scaler_summary and _histogram_summary and reinstall it.
