我想用它作为 mtplotlib.pyplot.boxplot 函数的输入。
我得到的错误matplotlib.pyplot.boxplot(mydataframe)
是ValueError: cannot set an array element with a sequence
我尝试使用list(mydataframe)
而不是mydataframe
. 失败并出现同样的错误。
我也试过matplotlib.pyplot.boxplot(np.fromiter(mydataframe, np.float))
- 失败了ValueError: setting an array element with a sequence.
