def quant_embedding(program, place, config=None, scope=None):
"""quantize lookup_table op parameters
Args:
program(paddle.static.Program): infer program
scope(paddle.static.Scope, optional): Scope records the mapping between variable names and variables, similar to brackets in programming languages. Usually users can use `paddle.static.global_scope() <https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api_cn/executor_cn/global_scope_cn.html>`_ . When ``None`` will use `paddle.static.global_scope() <https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api_cn/executor_cn/global_scope_cn.html>`_. Default : ``None``.
place(paddle.CPUPlace or paddle.CUDAPlace): This parameter represents the executor run on which device.
config(dict, optional): config to quantize. The keys are 'quantize_op_types'. For op in quantize_op_types, you can define 'quantize_type', \
'quantize_bits', 'dtype', 'threshold'. \
``quantize_type`` is quantize type, supported types are ['abs_max'], default is "abs_max".
``quantize_bits`` supported bits are [8] and default is 8.
``dtype`` is quantize dtype, supported dtype are ['int8'], default is 'int8'.
``threshold`` is threshold to clip tensor before quant. When threshold is not set, \
tensor will not be clipped.
Returns:
None
