tensorflow: Repeated "Already exists: Resource" errors when I increase my model size

System information

• Custom model built by creating convolutional network tf graph with SGD optimizer and running
• Windows 10
• TensorFlow installed from pip
• TensorFlow version (use command below): 1.12
• Python version: 3.6
• Running on cpu

I’ve created a convolutional network by making a custom graph for feed forward and using a tensorflow optimizer to train it (I’ve tried with SGD and Adam).

`sess = tf.Session()
optimizer = tf.train.GradientDescentOptimizer(learning_rate=.01)

input_size = 16
input_matrix = tf.placeholder(tf.float32, shape=[1,input_size,input_size])
label_ph = tf.placeholder(tf.float32, shape=[28*28])
model_out = Model.feed_forward(input_matrix)

init = tf.global_variables_initializer()
sess.run(init)

loss = tf.losses.mean_squared_error([tf.convert_to_tensor(label_ph, tf.float32)], [model_out])
train = optimizer.minimize(loss)
sess.graph.finalize()`

This is my graph definition. I know Model.feed_forward is opaque but it’s basically a series of functions that get variable weights and feed input through layers. Just to give you an idea here’s an example of a convolutional feed forward:

`def feed_input(input_tensors, filters, biases, stride, zero_pad=True):
        if zero_pad:
            pad_size = int((int(filters[0].shape[0]) + 1)/2 - 1)
            input_tensors = tf.map_fn(lambda inp:
                tf.pad(inp, [[pad_size, pad_size], [pad_size, pad_size]]), input_tensors)

        _, shape_x, _ = input_tensors.shape

        unflattened_output = tf.map_fn(lambda input_tensor: tf.convert_to_tensor([[[tf.add(tf.tensordot(curr_filter,
            ConvLayer.__get_input_slice__(input_tensor, x, y, tf.shape(curr_filter)[0]), 2), biases[filter_ind])
         for x in range(0, shape_x - curr_filter.shape[0] + 1, stride)]
         for y in range(0, shape_x - curr_filter.shape[0] + 1, stride)]
         for filter_ind, curr_filter in enumerate(filters)], dtype=tf.float32), input_tensors)

        shape_1, shape_2, shape_3, shape_4 = unflattened_output.shape

        return tf.reshape(unflattened_output, [shape_1 * shape_2, shape_3, shape_4])`

After defining my graph I am running a loop that gets some input and runs sess.run(train, feed_dict={input_matrix:img, label_ph:label_image}). If I make input_size smaller (e.g. 4) or if I reduce the number of layers in my network, everything runs fine and it does exactly what I expect it to do. However, when my network grows in the ways I just mentioned it consistently spits out these errors during sess.run(train, feed_dict={input_matrix:img, label_ph:label_image}):
