  • 服务器上使用matplotlib.pyplot绘图

    在linux服务器端执行python脚本,有时候需要画图,但是linux没有GUI界面,因此需要在导入matplotlib.pyplot库之前先执行

    import matplotlib as mpl
    mpl.use('Agg')

    再执行

    import matplotlib.pyplot as plt

    需要保存图片到指定的目录

    plt.savefig("/home/yourname/test.jpg") 

    直接执行 import matplotlib.pyplot as plt 会报错:
