Reset Labels for Labeled Nodes in LPA

Hi,

In "model.py" when building lpa as following code, the labeled nodes seem not to be reset in the loop. I am wondering if this is correct. thank you!
def _build_lpa(self):
label_mask = tf.expand_dims(self.label_mask, -1)
input_labels = label_mask * self.labels
label_list = [input_labels]

    for _ in range(self.args.lpa_iter):
        lp_layer = LPALayer(adj=self.normalized_adj)
        hidden = lp_layer(label_list[-1])
        label_list.append(hidden)
    self.predicted_label = label_list[-1]

AttributeError: module 'tensorflow' has no attribute 'set_random_seed'

Awesome work!

I came across this error running your code:

Traceback (most recent call last):
  File "main.py", line 10, in <module>
    tf.set_random_seed(seed)
AttributeError: module 'tensorflow' has no attribute 'set_random_seed'

set_random_seed() is deprecated and it has been moved to tf.random.set_seed()

please share ppt

This one is awesome, can you create a repo and share your ppt, or send me by email?
Thank you ~
