Model Builder Version: Model Builder Preview 16.3.0.2056001 Visual Studion Version: 16.10.0 Preview 2.0 Bug description Training fails. I worked one time when I used the builder to learn how to create a image classifier. The classifier I built also also worked. But for some reason, neither works now.

Steps to Reproduce

  1. Create a console app with Net 3.1 or Net 5.0 . Both fail.
  2. Add Machine Learning.
  3. Image Classification
  4. Local CPU
  5. Train . . . fails immediately with error window summary of log-file entry.

Expected Experience I expected the app to create the Image Classifier Model zip-file.

Actual Experience As described - Model Builder fails.

image Looks like somehow tensorflow.dll is not found

Can you go to the following path $(Your_VS_Install_Path)\Common7\IDE\Extensions\Microsoft\ModelBuilder\AutoMLService folder and confirm that tensorflow.dll is there? If not, usually a re-install should fix the problem.

djmquestorsoftware commented 3 years ago

Thank you for the prompt reply.

The folder: ..\Common7\IDE\Extensions\Microsoft\ModelBuilder is missing.

I found a tensorflow.dll in ..\IDE\CommonExtensions\Microsoft\ModelBuilder...

Do I copy the ModelBuilder folder to the ..\Extensions\Microsoft\ folder?

Even though the Visual Studio Installer displayed the ML.Net ModelBuilder (Preview) check box as checked, the builder was not listed in the "Installation details" panel. I unchecked and rechecked the box and the builder became listed but the missing folder still does not appear.

When I download and try to install the model builder, the installer says it's already installed.

No you don't need to, CommonExtension is the right place. Do you have other tensorflow distribution binary installed on your machine? For example, those installed from pip install tensorflow or conda install tensorflow?

Hi @djmquestorsoftware

Thanks for the response, it also seems that you have mlnet.cli installed. Can you try using that cli for image training and see if it works so I can rule out tensorflow binary problem.

LittleLittleCloud commented 3 years ago

@Oceania2018 It looks quite similar to this issue in tensorflow.net https://github.com/SciSharp/TensorFlow.NET/issues/144

Do you have any idea what causes it

djmquestorsoftware commented 3 years ago

Sorry, The MLNet.CLI does not work either. I reported this on a different thread.

The comment "It seems that on some processor some Tensorflow.dll does not work, because it lacks of AVX support" I believe does not apply to my case because TensorFlow did work before I encountered the current problem.

The problem might have been caused by disk errors. When this problem started, I ran the virus checker offline and no viruses were found. I ran ChkDsk /R /F on my C and D drives and many errors where found and fixed. However, I do not know what was found or what was fixed and I do not know what "fixed" means. However, after the ChkDsk, I re-installed tensorflow per MS documentation for the Model Builder. Also, the MLNet CLI instruction do not require downloading and installing anything. I just had to check a couple of ML Net related boxes in Visual Studio and in Visual Studio Installer.

@djmquestorsoftware We do receive a few tensorflow error reported on some quite old CPU without AVX support but your CPU is quite new (by quite new I mean it's after 2010) so yes you are right, it shouldn't be AVX instruction missing problems.

I am not quite sure why disk error might be the cause but I can start a thread with Haiping to keep investigating in. In the meanwhile, please let us know if running ChkDsk cmd fix the tensorflow error!

djmquestorsoftware commented 3 years ago

Thank you for your attention. You can close this for me.

I have removed all of the Visual Studio and NuGet stuff. I have checked for malicious code: None found. I have run ChkDsk twice and found no more errors. I am now re-installing Visual Studio 2019 (for my regular apps) and 2019 Preview (for the ML stuff), the mlnet CLI, and the ML.Net Model Builder. If something was corrupted, hopefully this re-install will correct the problem.
