根因分析

向plt.hist()传递了字符串列表作为bins参数，但该参数需要数值型bins或单个字符串方法（如'auto'、'fd'）。

English

Passing a list of strings as bins to plt.hist(), which expects numeric bins or a single string method (like 'auto', 'fd').

generic

解决方案

  1. 95% 成功率 Use an integer for the number of bins 
    plt.hist(data, bins=20)
  2. 90% 成功率 Use a sequence of bin edges as numbers 
    plt.hist(data, bins=[0, 10, 20, 30])

无效尝试

常见但无效的做法:

  1. Using a list of integers but with mixed types 80% 失败

    Bins must be numeric; mixed types cause conversion errors.

  2. Passing a single string like 'auto' but in a list 90% 失败

    A list of one string is still a list, not a valid bins argument.
