Tensorflow giving strange error in relation to variable reuse, stating a kernel already exists - tensorflow

Question

Fantastic news I figured this out and will keep the solution here for posterity.
I needed to begin my script with tf.restore_default_graph()
I am in the beginning stages of writing a GAN in Tensorflow, and I am getting a weird error message in regards to whether or not I intend to be reusing a variable. It is basically saying (I think) that I am trying to define a kernel twice for one of my convolutions. Code and error are attached. Thank you!
