使用tex作为pdf时保存matplotlib pyplot [英] Save matplotlib pyplot while using tex as pdf

问题描述

我正在使用matplotlib进行绘图.该图形已正确显示在jupyter笔记本中，但我无法将其另存为pdf.保存为 png 工作正常，但遗憾的是这不是我的选择.

I am making a plot using matplotlib. The graph is correctly displayed in jupyter notebook, but I am not able to save it as a pdf. Saving as a png works fine, but this is regrettably not an option for me.

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages

values= [[0,   -1.055], [2.5, -1.798], [6.5, -1.662], [9,   -1.274],
        [10,  -0.939], [11,  -0.527], [12,  -0.338], [15,   0.345],
        [17,  -0.146], [19,  -1.526], [19,  -1.395], [21,  -2.454]]

values= np.array(values)

fig = plt.figure(1, figsize=(9,6.5))

plt.rc('text', usetex=True)
plt.rc('font', family='serif')

plt.scatter(values[:,0], values[:,1])
plt.show()

pdf = PdfPages('test.pdf')
pdf.savefig(fig)
pdf.close()

我收到以下错误:

TypeError: a bytes-like object is required, not 'str'

我正在运行 python 3.6.3 |Anaconda custom (64-bit)|(默认值，2017年10月15日，03:27:45)[MSC v.1900 64位(AMD64)]和matplotlib版本2.1.0.
