贪婪采样器（GreedySampler）
GreedySampler 类
keras_nlp.samplers.GreedySampler(**kwargs)
贪婪采样器类。
此采样器基于贪婪搜索实现，即始终选择概率最大的标记作为下一个标记。
示例
causal_lm = keras_nlp.models.GPT2CausalLM.from_preset("gpt2_base_en")
# Pass by name to compile.
causal_lm.compile(sampler="greedy")
causal_lm.generate(["Keras is a"])
# Pass by object to compile.
sampler = keras_nlp.samplers.GreedySampler()
causal_lm.compile(sampler=sampler)
causal_lm.generate(["Keras is a"])
