Python Matplotlib xtick给出了;包含多个元素的数组的真值不明确;

Python Matplotlib xtick给出了;包含多个元素的数组的真值不明确;,python,python-3.x,matplotlib,Python,Python 3.x,Matplotlib,我正在尝试使用matplotlib绘制一些数据。问题是当我使用plt.xtick()函数时,它会给我以下信息 ValueError: The truth value of an array with more than one element is ambiguous.

我正在尝试使用matplotlib绘制一些数据。问题是当我使用plt.xtick()函数时,它会给我以下信息

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
下面是第60行的代码错误“plt.xticks(np.array([r+范围内r的条形宽度(len(ener))])),xlab,旋转=90)”

将numpy导入为np
从mpl_toolkits.mplot3d导入axes3d
将matplotlib.pyplot作为plt导入
将matplotlib.tri导入为tri
从matplotlib.ticker导入MaxNLocator
输入数学
导入操作系统,pdb
路径=[“1leo_5fpps_pwat”、“1leo_5fpps_u8”、“1leo_5fpps_u8_t4”]
氨基酸={1:“Ser1”,2:“trp2”,3:“thr3”,4:“trp4”,5:“glu5”,6:“gly6”,7:“asn7”,8:“lys8”,9:“trp9”,10:“thr10”,11:“trp11”,12:“lys12”}
np.set\u打印选项(suppress=True)
副本=0
f、 ax=plt.子批次(3,figsize=(15,10),sharex=True)
对于范围(3)中的i:
xf=np.rand.rand(6000199)
Z=np.平均值(xf,轴=0)
#设置条的宽度
条形宽度=0.25
#设置杆的高度
ener=Z[1::3]
vdw=Z[2::3]
elec=Z[3::3]
过滤指数=np。其中(ener使用

plt.xticks(np.数组([r+范围内r的线宽(len(ener))]),[''.join(x)表示xlab中的x],旋转=90)
这里的问题是

plt.xticks(A,B)
期望B是字符串列表

但是你把B作为一个66 x 2的numpy数组来填充。 因此,我们将这两个元素与

“”.join()

函数,并通过列表理解在66上迭代。

如果您可以指向导致此错误的行,这将非常有用。编辑文章以包含给出错误的行号。因此第60行给出错误。似乎xlab是一个具有形状(66,2)的数组。这似乎可行。您可以提供一些解释吗。
