Using a tf.Tensor as a Python bool is not allowed.

I want to do ： IF True: return a ; else : return b (in python) . But there is a error : Using a tf.Tensor as a Python bool is not allowed. How can I do this

c=tf.placeholder(tf.bool) if c : loss=-tf.reduce_sum(lable * tf.log(lable2))

raise TypeError("Using a tf.Tensor as a Python bool is not allowed. "
TypeError: Using a tf.Tensor as a Python bool is not allowed. Use if t is not None: instead of if t: to test if a tensor is defined, and use TensorFlow ops such as tf.cond to execute subgraphs conditioned on the value of a tensor.

This is intended. Please use tf.cond.
