Cannot load Tensorflow DLL error.

[JTrotta]

Any idea? obviously tensorflow.dll is in bin folder

Setting Eager mode...

@JTrotta I noticed there is a space in the lib name.

Please check the dll name:

[JTrotta]

@Oceania2018 No. The space is just a copy and paste error. The question is much more complicated.
It seems that on some processor some Tensorfow dll does not work, because it lacks of AVX support, have a look here https://github.com/fo40225/tensorflow-windows-wheel.

Now I'm using a custom DLL from https://github.com/fo40225/tensorflow-windows-wheel, and it'working. But during session dispose I receive a new error:

Any help on this?

[Oceania2018]

@JTrotta I use Windows 10 and compile the latest TensorFlow from source code. I've tested on several machines. So what's your environment? Actually, I can't open the link in your above post.

Did you try the simplest test like in the public void ScalarConst()?

[JTrotta]

@Oceania2018 I just updated links.
Yes, the error you see in picture, raises using this basic instructions:
// Launch the default graph. using(sess = tf.Session()) { var feed_dict = new Dictionary<Tensor, NDArray>(); feed_dict.Add(a, (short)2); feed_dict.Add(b, (short)3); // Run every operation with variable input Console.WriteLine($"Addition with variables: {sess.run(add, feed_dict)}"); Console.WriteLine($"Multiplication with variables: {sess.run(mul, feed_dict)}"); }

My enviroment is W7, with :

[Oceania2018]

@JTrotta Try to use 1.12 download from https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-windows-x86_64-1.12.0.zip

I just pushed some changes. pull and retry.

[Oceania2018]

@JTrotta Are you running BasicOperations in TensorFlowNET.Examples ?

[JTrotta]

@Oceania2018 Yes basic operations...Just trying ....
Nothing changes. Using this https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-windows-x86_64-1.12.0.zip I got the error "DLL not found" as before. Using this customized https://github.com/fo40225/tensorflow-windows-wheel/tree/master/1.12.0/py36/CPU/sse2, the addition and the mutiplcation are done, but session dispose goes in error.

[Oceania2018]

@JTrotta Can you check if the _handle of the Session is IntPtr.Zero? I can't reproduce on my local.

[JTrotta]

@Oceania2018 It does not seem:

[Oceania2018]

@JTrotta It's not an empty pointer. Will investigate more for this issue. Thanks for using TensorFlow.NET.

[dotChris90]

@JTrotta hm did you fork tensorflow.net? if yes you could commit your whole workspace to your repo (except bin and obj folder but with the tensorflow dll). don't do commit to main repo but to your fork.

We could clone your fork and check on our systems so we ensure we have some workspaces.

:) just a suggestion for better reproducing the error.
