    • ValueError – 如果state取值不在 [‘CPU’, ‘GPU’, ‘All’]中，或sorted_key取值不在 [None, ‘calls’, ‘total’, ‘max’, ‘min’, ‘ave’]中，则抛出异常。
    1. #### sorted_key = 'total', 'calls', 'max', 'min', 'ave' 结果 ####
    2. # 示例结果中，除了Sorted by number of xxx in descending order in the same thread 这句随着sorted_key变化而不同，其余均相同。
    3. # 原因是，示例结果中，上述5列都已经按从大到小排列了。
