# ### Convolution and Max Pooling Layer
# Convolution layers have a lot of success with images. For this code cell, you should implement the function `conv2d_maxpool` to apply convolution then max pooling:
# * Create the weight and bias using `conv_ksize`, `conv_num_outputs` and the shape of `x_tensor`.
# * Apply a convolution to `x_tensor` using weight and `conv_strides`.
# * We recommend you use same padding, but you're welcome to use any padding.
# * Add bias
# * Add a nonlinear activation to the convolution.
# * Apply Max Pooling using `pool_ksize` and `pool_strides`.
# * We recommend you use same padding, but you're welcome to use any padding.
