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

An error message “runtimeerror: expected one of cpu, cuda, xpu, mkldnn, opengl, opencl, ideep, hip, msnpu, xla, vulkan device type at start of device string: meta” typically occurs when you are specifying an incorrect device type or missing the device type declaration altogether. It usually happens in programming languages or frameworks that involve the use of GPUs or specialized hardware devices for computation.

For example, in Python, when using libraries like PyTorch or TensorFlow, you need to specify the device type at the start of your code to indicate whether you want to use a CPU or GPU for computations. The correct format should be something like:

    
import torch
  
# Specify the device type
device = torch.device('cpu')  # or 'cuda' if you have a GPU
  
# Rest of your code goes here
...
    
  

In the example above, we import the PyTorch library and then specify the device type as ‘cpu’ or ‘cuda’ using the `torch.device()` function. This ensures that the computations are performed on the desired device. If you specify an incorrect device type or miss this declaration, you might encounter the mentioned error message.
