Hi 

   Did find the solution?

Thanks

Kai

You could try this: R12 

However, if it is a new machine I would contact DELL technical support and discuss options with them since a new machine should not crash.

Thanks. I will call DELL tomorrow.

  Watchdog timeout is a cpu error?  Something todo with thread timing like a process has to recieve a response in a few milliseconds or u crash...   I thing even depending on the level of play  NoOverclock  could be a bad thing...

Called DELL today, updated all the drivers, still have the same issue. Run SupportAssist and check all the hardware, everything is good but that does not fix the problem. When run a simple Tensorflow Python code, it crushes (CLOCK_WATCHDOG TIMEOUT). 

Did you try the change documented here? : R12 bios setting 

I do not have an R12, so I cannot test this out. But it looks like several other users had great success in solving their issue with this change.

Does it only happen with Tensorflow Python code, or does it happen with other programs also?

So far I only installed Anaconda , run  Python program using Google Tensorflow. No there program installed.
