|
Context manager enabling the export mode. |
|
Check if the installed PyTorch version meets or exceeds a specified version. |
|
Get the parallel state. |
- export_torch_mode()
Context manager enabling the export mode.
- get_parallel_state(model, name=None)
Get the parallel state.
- Parameters:
model – Pytorch model.
name – The name of the submodule of the model to get the parallel state from. If None, the parallel state of the model is returned.
- Return type:
ParallelState
- is_quantized(module)
Check if a module is quantized.
- is_quantized_column_parallel_linear(module)
Check if a module is a quantized column parallel linear module.
- is_quantized_layer_with_weight(module)
Check if a module is quantized with weights.
- is_quantized_row_parallel_linear(module)
Check if a module is a quantized row parallel linear module.
- is_torch_library_supported()
Check if the installed PyTorch version meets or exceeds a specified version.
- reduce_amax(input, axis=None, keepdims=True)
Compute the absolute maximum value of a tensor.
Reduces input_tensor along the dimensions given in axis. Unless keepdims is true, the rank of the tensor is reduced by 1 for each entry in axis. If keepdims is true, the reduced dimensions are retained with length 1.
Note
Gradient computation is disabled as this function is never meant learning reduces amax
- Parameters:
input – Input tensor
axis – The dimensions to reduce. None or int or tuple of ints. If None (the default), reduces all dimensions. Must be in the range [-rank(input_tensor), rank(input_tensor)).
keepdims – A boolean. If true, retains reduced dimensions with length 1. Default True
granularity – DEPRECTED. specifies if the statistic has to be calculated at tensor or channel granularity
- Returns:
The reduced tensor.
- Raises:
ValueError – Any axis which doesn’t make sense or is not supported
ValueError – If unknown granularity is passed in.
- replace_function(package, name, new_func)
Replace a function with a new one within a context.
