TypeError when image_demo.py

[warriors30n11]

When I execute image_demo.py at the beginning, it occurs error like this:

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.

I search this problem on the Internet, but I still don't know where is the problem.
