TypeError:找不到直方图权重属性或关键字参数

Question

我试图利用“weights”属性或关键字参数生成一个直方图。但是，尽管它在过去起作用并且出现在帮助说明中，但现在它时不时地失败（见下文）。我尝试过安装和卸载Python，但它一直有相同的行为。我还从应用程序中移出了一个程序，里面有自己的pythons任务(casa.nrao.edu酒店). 在

我正在研究macos10.13.1（我想知道从10.12升级到10.13是否是主要问题）。我使用的是python2.7.14、matplotlibv2.1.1、numpy 1.13.3、ipython5.4.1（但在标准pythonshell中也是如此）。在

import matplotlib.pylab as plt

tmp=np.array([1,3,5,2])
wgt=tmp*0+1

np.histogram(tmp,weigths=wgt)

但时不时，np.直方图以及plt.hist公司工作，但不是斧头图. 在

任何指导都会很有帮助的！提前谢谢你！在
