Tensorflow 3 channel order of color inputs
<p>I'm using tensor flow to process color images with a convolutional neural network. A code snippet is below.</p>

<p>My code runs so I think I got the number of channels right. My question is, how do I correctly order the rgb data? Is it in the form rgbrgbrgb or would it be rrrgggbbb? Presently I am using the latter. Thanks. Any help would be appreciated.</p>
