tensorflow 在anaconda 环境下import matplotlib.pyplot失败

如下当你import matplotlib.pyplot 时就会出现下面的报错

/home/zph/anaconda2/envs/tensorflow/bin/python2.7 /home/zph/桌面/Joint-Bayesian-master/src/testTensorflow.py

Traceback (most recent call last):

    import matplotlib.pyplot as plt

不是版本兼容问题

系统编码是ascii 不识别uft8

解决方案

import sys
reload(sys)
sys.setdefaultencoding('utf8')

放在py文件最前面
