`torch.arccos` is a function in PyTorch used to calculate the element-wise inverse cosine (arccosine), which has the same functionality as `torch.acos`.
### Function Definition
torch.arccos(input, out=None)

## Usage Example
## Example
import torch
# Create tensor
x = torch.tensor([-1.0, -0.5,0.0,0.5,1.0])
# Compute arccos
result = torch.arccos(x)
print(result)
The output result is:
tensor([3.1416, 2.0944, 1.5708, 1.0472, 0.0000])
