what is numel function in pytorch?

''' PyTorch torch.numel() method returns the total 
number of elements in the input tensor.'''
# Importing the PyTorch library  
import torch  
    
# A constant tensor of size n 
a = torch.randn(4, 6) 
print(a) 
  
# Applying the numel function and  
# storing the result in 'out' 
out = torch.numel(a) 
print(out)
