Dear forum members.

I have recently installed DLS and trying to run already built project, MNIST Handwritten Digits Classifier. Under training tab when I click “Start Training” , I receive following message “Error in connecting to compute server.”

Please do help me out, how to run model.

Thanks a lot.

There is no error in the logs . Do you have anti-virus on your system ?

There is another user who faced the same issue and it was eventually narrowed to the anti-virus blocking the compute server port.

Please go through this thread:

Thank you. I will try this out.

#7

Dear Rajendra,

I have deactivated anti-virus and firewalls (uninstalled - re-installed DLS) but still I am getting same error.

#8

ok. Can you try the steps mentioned in the thread (post#7)?

#9

I found the problem, it was proxy settings in the Browser. I have removed proxy server and now its running fine.

Thank you for your support.
