Detecting problems。

Hello, I can work when I train, and train the .h5 model, but when testing with YOLO_pred.py ,the error is reported as follows: 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.
