Just playing with your VdCnn sample, which throws excpetion 'Unable to find an entry point namend 'AddControlInput' in DLL tensorflow. Happens on that line:

                   // batch normalization
                    conv = tf.layers.batch_normalization(conv, training: is_training);

The references are SciSharp.TensorFlow.Redist v1.14.0 and TensorFlow.NET v0.10.3

Thanks for your help!

Have to replace tensorflow with this one: https://github.com/SciSharp/TensorFlow.NET/tree/master/tensorflowlib/runtimes/win-x64/native

Hi! I just upgraded to your latest TensorFlow.NET 0.10.10 and used the dll you provided.

Now I get 'can't get graident function through get_gradient_function TopKV2' on this line:

           tf_with(tf.control_dependencies(update_ops.Select(x => (Operation)x).ToArray()), delegate
            {
                var adam = tf.train.AdamOptimizer(learning_rate);
                adam.minimize(loss, global_step: global_step);
            });
