PlaceholderObserver¶
- class torch.quantization.observer.PlaceholderObserver(dtype=torch.float32, custom_op_name='', compute_dtype=None)[source]¶
Observer that doesn’t do anything and just passes its configuration to the quantized module’s
.from_float().Can be used for quantization to float16 which doesn’t require determining ranges.
- Parameters:
dtype – dtype argument to the quantize node needed to implement the reference model spec.
custom_op_name – (temporary) specify this observer for an operator that doesn’t require any observation (Can be used in Graph Mode Passes for special case ops).
compute_dtype – if set, marks the future quantize function to use dynamic quantization instead of static quantization. Note: this field will be removed in the near future and replaced with is_dynamic.
