来自matplotlib.pyplot import plt ImportError：没有名为'matplotlib'的模块

Question

I'm on linux mint 18.3. I can import matplotlib fine, but I need to plot something from a certain file. When I try to plot something simple, I get this error:

python3 spline.py
Traceback (most recent call last):
File "spline.py", line 2, in <module>
from matplotlib.pyplot import plt
ImportError: No module named 'matplotlib'

my code in the file is:

from matplotlib.pyplot import plt

plt.plot([1, 2, 3],[2, 4, 6])

plt.show()

already tried:

pip install matplotlib
sudo apt-get install python-matplotlib
sudo apt-get install python3-matplotlib

Answer 1

我想在你的代码中你应该使用

import matplotlib.pyplot as plt

Answer 2

Nevermind guys the thing was the way I was importing it, the "correct" way is:

from matplotlib import pyplot as plt

that's all now it's working
