我正在尝试运行一个非常简单的代码,在集群中输出.png文件.这是代码:

import matplotlib.pyplot as plt
import numpy as np

x = np.random.randn(60)
y = np.random.randn(60)

plt.scatter(x, y, s=20)

out_png = 'path/to/store/out_file.png'
plt.savefig(out_png, dpi=150)

如果我使用python simple_code.py安装了matplotlib 1.2.1的系统中的命令运行此代码,我会收到警告:

Unable to load library icui18n "Cannot load library icui18n:

.png图像仍然生成,所以我没有问题.但是如果我在安装了matplotlib 1.3.0的集群中使用相同的命令和代码,则会失败并显示错误:
