Tensorflow Illegal Instruction

[GeovaneW96]

Hi,

I use TensorFlow.NET in my application and it works fine in my PC. But, when installing at a Windows Server, I get a Faulting module exception for tensorflow.DLL.

Environment:
Windows Server R2 2012

Build:
Tensorflow.NET v0.12.0 (tried other versions too)
SciSharp.TensorFlow.Redist (CPU) 1.15.0 (tried other version too)
Target platform x64

Error:

When running from Visual Studio the only ouput is "Application exited with code 0xc000001d Illegal Instruction"

Just got an extra info..

System.DllNotFoundException: Unable to load DLL 'tensorflow': A dynamic link library (DLL) initialization routine failed. (Exception from HRESULT: 0x8007045A) at Tensorflow.c_api.TF_NewGraph() at Tensorflow.Graph..ctor()

Could make it work by downloading tensorflow.dll from here:

https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-windows-x86_64-1.3.0-rc2.zip

Resolved? You could download from here as well.

I had already tried downloading those versions through NuGet...

And it's actually not resolved...
I just ended up with a new problem.

This exception is now thrown when initializing the Graph:
Exception thrown: 'System.EntryPointNotFoundException' in TensorFlow.NET.dll
Exception thrown: 'System.Reflection.TargetInvocationException' in mscorlib.dll
NodeDef mentions attr 'dilations' not in Op<name=Conv2D; signature=input:T, filter:T -> output:T; attr=T:type,allowed=[DT_HALF, DT_FLOAT]; attr=strides:list(int); attr=use_cudnn_on_gpu:bool,default=true; attr=padding:string,allowed=["SAME", "VALID"]; attr=data_format:string,default="NHWC",allowed=["NHWC", "NCHW"]>; NodeDef: module_apply_default/MobilenetV1/MobilenetV1/Conv2d_0/Conv2D_Fold = Conv2D[T=DT_FLOAT, data_format="NHWC", dilations=[1, 1, 1, 1], explicit_paddings=[], padding="SAME", strides=[1, 2, 2, 1], use_cudnn_on_gpu=true](module_apply_default/hub_input/FakeQuantWithMinMaxArgs_1, module_apply_default/MobilenetV1/MobilenetV1/Conv2d_0/weights_quant/FakeQuantWithMinMaxVars). (Check whether your GraphDef-interpreting binary is up to date with your GraphDef-generating binary.).
Exception thrown: 'Tensorflow.TensorflowException' in TensorFlow.NET.dll

And also this:

System.TypeInitializationException: The type initializer for 'Tensorflow.Binding' threw an exception. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.EntryPointNotFoundException: Unable to find an entry point named 'TFE_NewContextOptions' in DLL 'tensorflow'. at Tensorflow.c_api.TFE_NewContextOptions() at Tensorflow.tensorflow..ctor() --- End of inner exception stack trace --- at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.Activator.CreateInstanceT at Tensorflow.Binding.NewT at Tensorflow.Binding..cctor() --- End of inner exception stack trace --- at Tensorflow.Binding.get_tf() at LayoutRecognizer.ReadTensorFromImageFile(String file_name, Int32 input_height, Int32 input_width, Int32 input_mean, Int32 input_std)

Seems like Tensorflow.NET is not compatible with tensorflow 1.3.0?

@GeovaneW96 You should keep the tensorflow dll version compatile with the model trained version.

[GeovaneW96]

Ok.
I trained my models with tf v 1.14
I'll try downgrading to v1.13.0rc2 and i'll come back.

Did you solve this issue? I am currently having the same issue, also using an Intel Xeon CPU, could this be the problem?
