Python EPS 可视化错误

我安装了一个名为 YT 的用于数据分析的开源 Python 平台，并尝试运行具有以下导入的 Python 脚本：

import yt
import numpy as np
import yt.visualization.eps_writer as eps
from yt.data_objects.particle_filters import add_particle_filter
from matplotlib import pyplot as plt
plt.switch_backend('agg')

但是，我收到无法找到模块 pyx 的错误：

> Traceback (most recent call last):   File "gasinflow.py", line 3, in
> <module>
>     import yt.visualization.eps_writer as eps   File "/home/samvad/anaconda3/lib/python3.6/site-packages/yt/visualization/eps_writer.py",
> line 16, in <module>
>     import pyx ModuleNotFoundError: No module named 'pyx'

Python 版本：3.6 我遇到过这个问题，Cython 未安装，但 Cython-0.29.7 也已安装。

看起来你只需要安装 pyx：

~$ pip3 install pyx
Collecting pyx

我建议始终使用它pip来安装模块，因为它可以获取任何模块所需的任何依赖项。
