无法在 Z23EEEB4347BDD26BFC6B7EE9A3B75 的 Ubuntu 中导入 numpy 和 scipy。

Question

我正在尝试将numpy和scipy加载到我的 Ubuntu 虚拟机中。

我已确保两者都已安装：

con@VB:~/Scripts$ pip3 install numpy
Requirement already satisfied: numpy in /usr/local/lib/python3.6/dist-packages (1.14.2)
con@VB:~/Scripts$ pip3 install scipy
Requirement already satisfied: scipy in /usr/local/lib/python3.6/dist-packages (1.1.0)
Requirement already satisfied: numpy>=1.8.2 in /usr/local/lib/python3.6/dist-packages (from scipy) (1.14.2)

但是当我到达python3时：

con@VB:~/Scripts$ python3
Python 3.6.8 (default, Oct  7 2019, 12:59:55) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy

我收到了这个可怕的信息：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/numpy/__init__.py", line 142, in <module>

    print 'string matches'
                         ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('string matches')?
Error in sys.excepthook:

    print 'string matches'
                         ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('string matches')?

Original exception was:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/numpy/__init__.py", line 142, in <module>

    print 'string matches'
                         ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('string matches')?

这个错误似乎是关于从 python2 切换到 python3 以及 print 语句所需的括号的新手错误，但我没有编写任何这些文件。

我检查了 Python 中的“SyntaxError: Missing parentheses in call to 'print'”是什么意思？ 和无法在 python3 中导入 numpy以及如何为 Python 3.6 安装 NumPy但找不到任何有用的解决方案

如何在 python3 中加载 numpy 和 scipy？

Answer 1

你有语法错误。 在 python3 中，您需要使用print("string") 。 不print 'string' 。
