In the labs while trying to train the models, I am getting error “the kernel has died” frequently and not able to proceed due to the same. Is anyone else getting the same error? Any suggestion on what to do? ---

Please check if you selected the right size for your virtual machine. The recommended instance is **Ml.m5.2xlarge** , and it will create a **8 CPU 32 GB** VM. ---

I had the same problem with Lab 2. I was unable to select any kernel instance with \> 4GB RAM, so the train() functions would fail after exausting the 4GB RAM.

You can only select the bigger instance with the exact name shown in the lab instructions. When I did it, the name was: **ml.m5.2xlarge**. ---

Thanks, Leonardo. Must have misread that!
