Runtimeerror: expected one of cpu, cuda, xpu, mkldnn, opengl, opencl, ideep, hip, msnpu, xla, vulkan device type at start of device string: meta

This error usually occurs when specifying the device type incorrectly in the code. The device type should be one of the supported options such as cpu, cuda, xpu, mkldnn, opengl, opencl, ideep, hip, msnpu, xla, or vulkan.

The device type determines the backend hardware/device that will be used for computation.

Here’s an example to illustrate how to specify the correct device type:

            
import torch

# Correct device type - using 'cpu' as the device type
device = torch.device('cpu')

# Incorrect device type - using 'meta' as the device type
device = torch.device('meta')
            
        

In the above example, the correct way to specify the device type is by using ‘cpu’, which represents the CPU device. However, specifying ‘meta’ as the device type would result in the mentioned error.
