Some tips about Tensorflow

Q: How to fix error report like

A: We can’t feed a value into a variable and optimize it in the same time (So the problem only occurs when using Optimizers). Should using ‘tf.assign()’ in graph to give value to tf.Variable

Q: How to get a tensor by name?

      I think in Tensorflow we could accept value into a placeholder and then assign its value to a variable. The snippet below could work well:
