title: Set weight and bias tensors of tensorflow conv2d operation
body: <p>I have been given a trained neural network in torch and I need to rebuild it exactly in tensorflow. I believe I have correctly defined the network's architecture in tensorflow but I am having trouble transferring the weight and bias tensors. Using a third party package, I converted all the weight and bias tensors from the torch network to numpy arrays then wrote them to disk. I can load them back into my python program but I cannot figure out a way to assign them to the corresponding layers in my tensorflow network. </p>
  
  <p>For instance, I have a convolution layer defined in tensorflow as</p>
  
  <pre><code>kernel_1 = tf.Variable(tf.truncated_normal([11,11,3,64], stddev=0.1))
  conv_kernel_1 = tf.nn.conv2d(input, kernel_1, [1,4,4,1], padding='SAME')
  biases_1 = tf.Variable(tf.zeros[64])
  bias_layer_1 = tf.nn_add(conv_kernel_1, biases_1)
  </code></pre>
  
  <p>According to the tensorflow documentation, the tf.nn.conv2d operation uses the shape defined in the kernel_1 variable to construct the weight tensor. However, I cannot figure out how to access that weight tensor to set it to the weight array I have loaded from file. </p>
  
  <p><strong>Is it possible to explicitly set the weight tensor? And if so, how?</strong> </p>
  
  <p>(The same question applies to bias tensor.)</p>
