在 Ubuntu 中安装 scipy

tag-icon • tag-icon python installation
在 Ubuntu 中安装 scipy

所以每当我尝试

pip install -U scikit-learn

我得到：

ImportError: libatlas.so.3gf: cannot open shared object file: No such file or directory

我确定我atlas-base的目录中有/usr/lib/。我做错了什么？

编辑：澄清一下，我在虚拟环境中执行此操作。

编辑2：有人建议我使用sudo apt-get install python-scipy，这是我尝试导入时得到的结果：

>>> import sklearn

编辑3：修复了numpy的一些依赖问题之后，我现在得到：

   import fblas
ImportError: libatlas.so.3gf: cannot open shared object file: No such file or directory

答案1

要获取依赖项，请尝试

sudo apt-get install python python-dev libatlas3-base-dev gcc gfortran g++

另外，你应该检查 numpy 是否是最新的：

>> 导入 numpy

>> numpy.version.版本

‘1.6.1’

（例如）。我认为您需要 numpy > 1.5.0 以获得最新的 scipy 发行版。

然后您可以尝试sudo apt-get install python-scipy其他答案中建议的命令。

答案2

sudo apt-get 安装 python-sklearn

编辑：

hdante@aielwaste:~$ python

>>> import sklearn
>>>

答案3

sudo apt-get install python-scipy

答案4

我可以

echo "/usr/lib/atlas-base" | sudo tee /etc/ld.so.conf.d/atlas-lib.conf
sudo ldconfig
