Local azmlinfsrv script returns Access is Denied

Schibli, Eric 46

I recently was issued a new machine, and running the azmlinfsrv command returns "Access is Denied," regardless of whether it is run in a conda or virtuanenv environment. I have tried following the tutorial line-for-line, starting with a fresh envrionment, installing only azureml-inference-server-http , and providing a "hello world" entry script. Manually running the generated azuremlinfsrv.exe script in Explorer returns a similar error message, even with elevation. User's image

Hello @Schibli, Eric , Thanks for using Microsoft Q&A Platform.

Maybe you can try these troubleshooting steps:

Ensure that you have necessary permissions on your machine/directories.

Make sure your environment path is set up correctly and that there are no conflicting installations. Delete the existing environment and create a new one. (if you haven't tried already)

Sometimes installation files can become corrupt. Try uninstalling and reinstalling the package.

Please check these steps related to this error: Windows cannot access the specified device, path, or file" error when you try to install, update or start a program or file

@Schibli, Eric Did you install virtualenv and then start the virtual environment through activate.bat?

I ran these commands on my windows machine before starting the virtual environment.

pip install virtualenv
python -m virtualenv myenv
cd myenv\Scripts
activate.bat

python -m pip install azureml-inference-server-http

**Create the scoring script. The script might have incorrect syntax but that can be** **corrected if there is an error after azmlinfsrv command**

echo -e "import time def init(): \n\t time.sleep(1) \n\n def run(input_data): \n\t return {"message":"Hello, World!"}" > score.py

**Run scoring script**

azmlinfsrv --entry_script score.py

The output of my command is below: User's image

Please check if this helps!! Thanks!!

Good morning @romungi-MSFT - As I noted in my original post, I followed the tutorial, running those commands in sequence. This yields the "Access is denied." error:

Thanks - I have already tried reinstalling Conda, starting fresh venvs, and confirming read/write permissions on both the environment and working directory. And as I noted in my initial comment I tried with elevation as well to rule out permissions issues - same error.

@Schibli, Eric I can confirm that this worked in my case where I have full access as owner, not sure if any administrative setting is denying access in your case. For example, the folder in which I ran the steps has the following permissions. This is the screenshot from my folder properties -> Security -> Advanced.

@Schibli, Eric Did you get a chance to check if the permissions are similar to mine in your case while running the above commands?

Hi @romungi-MSFT - I did, they are the same. I escalated the issue to our cybersecurity team and they determined that the issue is caused by Microsoft Defender blocking execution of the azmlinfsrv.exe script.

Hi @romungi-MSFT - Yes I checked the permissions and they are similar. I raised the issue with our cybersecurity team and they confirmed that the issue was caused by attack surface reduction in Microsoft Defender was blocking execution of the azmlinfsrv.exe script.

Thanks @Schibli, Eric

I am not familiar with MS defender, you could probably try on another network or machine which is not monitored by defender.
