从anaconda Windows执行此程序时，使用anaconda下的console 3.6
python simple_plot.py
运行，但不显示任何内容：
#file simple_plot.py
import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4])
plt.show()
如果我添加
%matplotlib inline
并运行程序：
python simple_plot.py
(base) C:\Users\idf\Documents\Python Scripts>python simple_plot.py
File "simple_plot.py", line 3
%matplotlib inline
^
SyntaxError: invalid syntax
如果我运行此程序
(base) C:\Users\idf\Documents\Python Scripts>python -c "import matplotlib; print(matplotlib.get_backend())"
我得到输出：
Qt5Agg
一旦包含以下内容，甚至没有简单的打印语句：
import matplotlib.pyplot as plt
print("hello world") #nothing shows on console
