python - Python Django NSException 的问题
问题描述
我正在使用并且正在尝试使用Django并且Python我正在尝试使用绘制一个简单的图表matplotlib并且我不断收到下面显示的错误。
Python之后也崩溃了。
mac如果有帮助，我正在使用。
Matplotlib版本“3.1.0”
我已经尝试过使用最简单的图表，但问题仍然存在。
这是我在views.py文件中的代码
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.backends.backend_agg import FigureCanvasAgg
import random
def get_svg(request):
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)
fig, ax = plt.subplots()
ax.plot(t, s)
ax.set(xlabel='time (s)', ylabel='voltage (mV)',
title='Sample')
ax.grid()
response = HttpResponse(content_type = 'image/png')
canvas = FigureCanvasAgg(fig)
canvas.print_png(response)
return response
这是我收到的错误消息：
