问题[numpy](ubuntu)

我以前有 numpy 工作过。不知道发生了什么，但现在我收到导入错误：

>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy

我已尝试按照其他答案中的建议使用 pip 和 apt （导入错误：名为 numpy 的模块）卸载和重新安装 numpy，但这并没有解决我的问题。它说我有最新版本的 numpy：

$ sudo apt install python-numpy
Reading package lists... Done
Building dependency tree       
Reading state information... Done
python-numpy is already the newest version (1:1.13.3-2ubuntu1).
The following packages were automatically installed and are no longer required:
  libllvm6.0 libllvm6.0:i386 libllvm7 libllvm7:i386
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 79 not upgraded.
$ python -c "import numpy"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named numpy

顺便提一下，numpy 在 python3 中运行良好。

今天我通过安装另一个包

pip3 install seaborn

这样做之后，我的熊猫包似乎坏了，我不知道如何修复它。我试图卸载并重新安装 pandas、numpy 和 seaborn，但总是得到同样的错误。

"Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

我怎样才能解决这个问题？

我试图通过这个链接在我的 ubuntu 16.04 上安装 python 3.7 。它正在安装它而没有任何错误，它返回：

which python3.7
/usr/local/bin/python3.7

当我运行时，我还有其他 python 版本（3.5 和 2.7）：

which python
/usr/bin/python

但我不能在 3.7 中导入 numpy ：

python3.7
Python 3.7.2 (default, Feb 19 2019, 13:25:43)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'numpy'
>>>

我试图安装 numpy ：

python-numpy is already installed at the requested version (1:1.11.0-1ubuntu1)

此外，我在 3.5 中没有这个问题：

python3.5
Python 3.5.2 (default, Nov 12 2018, 13:43:14)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>>

有人能告诉我这里有什么问题吗？！！！我该如何解决这个问题？

我尝试使用以下方法安装 numpy：pip install numpy

它有效，但我收到警告： warnings.warn(warning, RequestsDependencyWarning).

然后我尝试使用：安装 scipy，python -m pip install --user scipy 它起作用了。我已经检查了我的包列表：pip freeze以及它们都在列表中的位置：numpy==1.15.1 scipy==1.1.0 但是当我尝试在我的代码中导入它们时，出现以下错误。

ImportError: 
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

原来的错误是：

/home/spyros/.local/lib/python2.7/site-packages/numpy/core/multiarray.so: undefined symbol: PyUnicodeUCS2_FromObject

我尝试以相同的方式再次安装numpy，结果是一样的。你能帮我解决这个问题吗？

基本上，当我打电话时，pypy3 -m pip install numpy --user我会被抛出这个可爱的烂摊子：

  Add `--force` to your command to use it anyway if you must (unsupported).

我无法粘贴所有内容，因为它太长了

无论如何，我有最新版本的 PyPy 6.0.0 和最新版本的 pip 10.0.1。我正在运行 Ubuntu 16.04 作为 Linux 的 Windows 子系统。

我注意到的一件事是我运行的 pip 实际上位于 python3.5 中。问题是，我get-pip.py直接使用 PyPy 网站上的文件为 PyPy 安装 pip。

这是版本信息：

  pypy3 -m pip -V
  pip 10.0.1 from /home/r392781/.local/lib/python3.5/site-packages/pip (python 3.5)

我想我已经尝试了很多不同站点的所有内容，但仍然没有。有点不知所措。

最后一件事，numpy 在使用python3而不是pypy3.

我不确定这是否相关，因为这是 Ubuntu 交换，但我在 Windows 上安装了 PyPy3 和 pip。在这种情况下，pip 被单独安装在 pypy3 目录中，但是当我尝试安装 numpy 时，我得到了同样的大量错误。

我安装了Python3.6，如下所述：

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6

然后我按如下方式安装了numpy：

sudo apt-get install python3-numpy

我想我可以从 Python3.5 导入 numpy，但不能从 Python3.6

如何解决这个问题？

我想在 python 中工作。当我导入 scipy 或 numpy 时，它会显示以下错误：

saikat@saikat:~/Downloads/Python-2.7.15$ python
Python 2.7.14 |Anaconda, Inc.| (default, Dec  7 2017, 17:05:42)

>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy
>>> 

但是当我使用这个命令时：

sudo pip install numpy scipy

表明：

saikat@saikat:~/Downloads/Python-2.7.15$ sudo pip install numpy scipy

我应该怎么办？

我的电脑里有 python3.5 和 python3.6。当我尝试在 numpy3.6 中导入 python 时，出现错误。当我尝试通过安装 numpy 时sudo pip3 install numpy，我收到消息Requirement already satisfied: numpy in /home/user/.local/lib/python3.5/site-packages。如何为 python 3.6 安装 numpy？

这是我在导入 numpy 时遇到的异常：

谢谢

我收到导入错误：名为numpy. 这是否意味着我必须安装numpy？我已经下载了新版本，将其解压到家中。我不知道还能做什么。我正在使用 Ubuntu 16.04。我也试过：

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

但错误仍然存​​在。谁能指导我如何解决这个问题

我正确安装了conda。

现在我想将 Numpy 与默认附带的 Python-3.4.2 一起使用。

这是我运行的以及我得到的错误：

 conda install python3-numpy
Fetching package metadata: ....
Error: No packages found in current linux-32 channels matching: python3-numpy

Did you mean one of these?

    python-ntlm

You can search for this package on Binstar with

    binstar search -t conda python3-numpy
begueradj@begueradj-HP-Compaq-6510b-KE130ET-ABF:/home$ binstar search -t conda python3-numpy

我该如何解决这个问题？
