In the assignment notebook it says make sure 8vCPU+32Gib is selected for kernel. 2vCPU+4Gib is the Kernel auto assigned by Sagemaker for me and I get permission error when I try changing it to something higher. I go on through the lab but when I try execute trainer.train() in section 2 Fine Tune the model with the preprocessed dataset I get an error after a minute or so that **The kernel for Lab\_2\_fine\_tune\_generative\_ai\_model.ipynb appears to have died. It will restart automatically.** After this I have gone back and attempted twice but get the same error. ![image](https://global.discourse-cdn.com/dlai/original/3X/0/8/0814b50d92eee1b4def1506a0cdd5a1c3aa58568.png) ml.t3.medium is default kernel and I am unable to select anything else ---

I attempted to redo the lab again by relaunching amazon sagemaker after the “kernel died” error mentioned above but got the error below. File Save Error for Lab\_2\_fine\_tune\_generative\_ai\_model.ipynb Invalid response: 403 Forbidden ---

Hi. It seems you’re using a different instance type. Please check the screenshot in the notebook and make sure you’re selecting the one specified there. It’s most likely `ml.m5.2xlarge` but please double check. Almost all errors like this stems from that. Hope this helps! ---

When I open the lab notebook I get the default instance type as shown here Instance type: ml.t3.medium 2vCPU+4GiB. When I try to change it the option ml.m5.2xlarge you have suggested is not even available for selection as you can see from the screen shot above. When I try to select anything among the available choices I get this error(Failed to start Kernel.

Hi. `ml.m5.2xlarge` is below the “All Instances” section in your screenshot above. It is further down. It is not under the “Fast Launch” section. I just tested it yesterday and was able to find it. ---

Chris favila Thanks very very much. Your confident assertion made me look even more carefully at the button to click for getting all the selections. ---
