SGX driver device error while running pytorch example.

[mayank64ce]

Description of the problem

I am trying to run the pytorch ppml example, but when I try to run the example with SGX Enclave , I get SGX driver device error.

Steps to reproduce

Follow steps from PyTorch PPML Tutorial.

Expected results

Generation of result.txt with correct prediction.

Actual results

Gramine is starting. Parsing TOML manifest file, this may take some time...
error: Cannot open SGX driver device. Please make sure you're using an up-to-date kernel or the standalone Intel SGX kernel module is loaded.
error: load_enclave() failed with error: No such file or directory (ENOENT)

Gramine on Ubuntu 23 with jammy

What kernel version are you using? Also what hardware are you running this on?

[mayank64ce]

My kernel version is 6.5.0-44-generic on Ubuntu 23.

I was unable to find a package for mantic so I installed jammy instead.

@mayank64ce: Thanks for the info! 12th Gen Intel(R) Core(TM) i5-12600K does not support SGX (as implied by the output of lscpu CPU flags, also see the product spec).

[mayank64ce]

thanks @kailun-qin .. I understand. Closing the issue now.
