conda python没有使用numpy版本，如果我还指定它应该使用python 2，我会尝试安装 [英] conda python isn't using the numpy version I try install if I also specify that it should use python 2
问题描述
我正在尝试使用condas安装使用python 2.7和numpy版本1.10的环境
I am trying to use condas to install an environment that uses python 2.7 and numpy version 1.10
我尝试创建这样的环境
conda create -n test2 python=2.7 numpy=1.10
它表明它将安装我指定的软件
It contends it is going to install the software I specified
将安装以下新软件包:
The following NEW packages will be INSTALLED:
mkl: 11.3.3-0
numpy: 1.10.4-py27_2
openssl: 1.0.2l-0
pip: 9.0.1-py27_1
python: 2.7.13-0
readline: 6.2-2
setuptools: 27.2.0-py27_0
sqlite: 3.13.0-0
tk: 8.5.18-0
wheel: 0.29.0-py27_0
zlib: 1.2.8-3
然后激活它并运行python
and then activate it and run python
source activate test2
python
它通知我我正在使用python版本2.7.13，然后尝试检查numpy版本号
it informs me I am using python version 2.7.13 and then I try check the numpy version number
import numpy
numpy.version.version
它告诉我我有版本
'1.13.0'
'1.13.0'
这不是我指定的版本.另一方面，如果我跳过指定python版本，它将安装python 3，但安装了正确版本的numpy(1.10.4)
which is not the version I specified. On the other hand, If I skip specifying the python version, it installs python 3, but the correct version of numpy (1.10.4)
关于这里发生的事情有什么想法吗?此外，我该如何解决?谢谢！
Any ideas about what is going on here? Furthermore, how do I fix this? Thanks!
根据Uvar的评论
conda create -n test4 python=2.7 numpy=1.10 --no-deps
告诉我
将安装以下新软件包:
The following NEW packages will be INSTALLED:
numpy: 1.10.4-py27_2
python: 2.7.13-0
但是如果我source activate test4并检查numpy版本号，它会告诉我我再次运行1.13.0.
but then if I source activate test4 and check the numpy version number, it tells me I am running 1.13.0 again.
编辑2(再次响应Uvar的查询):
Edit 2 (Again in response to a query by Uvar):
conda list -n test2
返回
/home/ohnoplus/anaconda3/envs/test2中的环境中的#个软件包:
# packages in environment at /home/ohnoplus/anaconda3/envs/test2:
#
mkl 11.3.3 0
numpy 1.10.4 py27_2
openssl 1.0.2l 0
pip 9.0.1 py27_1
python 2.7.13 0
readline 6.2 2
setuptools 27.2.0 py27_0
sqlite 3.13.0 0
tk 8.5.18 0
wheel 0.29.0 py27_0
zlib 1.2.8 3
如果我source activate test2然后在python import numpy和numpy.__file__内部，则得到以下内容
Edit 3:
If I source activate test2 and then inside of python import numpy and numpy.__file__ I get the following
'/home/ohnoplus/.local/lib/python2.7/site-packages/numpy/__ init __.pyc'
'/home/ohnoplus/.local/lib/python2.7/site-packages/numpy/__init__.pyc'
同时，如果在python之外，但在test2内，我echo $PATH
meanwhile if outside of python, but inside of test2, I echo $PATH
我知道
/home/ohnoplus/anaconda3/envs/test2/bin:/home/ohnoplus/anaconda3/bin:/home/ohnoplus/bin:/home/ohnoplus/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
/home/ohnoplus/anaconda3/envs/test2/bin:/home/ohnoplus/anaconda3/bin:/home/ohnoplus/bin:/home/ohnoplus/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
@Uvar和@MSeifert指出我应该将路径变量指向正确的位置.我将尝试正确解决这个问题，但是我有两个问题:
Edit 4: @Uvar and @MSeifert point out that I should get my path variables pointing in the right place. I'll experiment with getting this right but I have a couple of questions:
我注意到，如果我查看sys.paths，则test2中的python sys.path似乎在寻找numpy的正确位置.
I notice that the python sys.path in test2 appears to be looking in the right place for numpy if I look at sys.paths
import sys
print (sys.path)
[''，'/home/ohnoplus/anaconda3/envs/test2/lib/python27.zip'，'/home/ohnoplus/anaconda3/envs/test2/lib/python2.7'，'/home/ohnoplus /anaconda3/envs/test2/lib/python2.7/plat-linux2'、'/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/lib-tk'、'/home/ohnoplus/anaconda3/envs /test2/lib/python2.7/lib-old'、'/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/lib-dynload'、'/home/ohnoplus/.local/lib/python2. 7/site-packages"，"/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/site-packages"，"/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/site-包/setuptools-27.2.0-py2.7.egg']
['', '/home/ohnoplus/anaconda3/envs/test2/lib/python27.zip', '/home/ohnoplus/anaconda3/envs/test2/lib/python2.7', '/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/plat-linux2', '/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/lib-tk', '/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/lib-old', '/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/lib-dynload', '/home/ohnoplus/.local/lib/python2.7/site-packages', '/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/site-packages', '/home/ohnoplus/anaconda3/envs/test2/lib/python2.7/site-packages/setuptools-27.2.0-py2.7.egg']
是否应该按照命令行，此sys.path变量或其他内容引用的方式更新$ PATH?
Should I be updating $PATH in as referenced in the command line, this sys.path variable, or something else?
推荐答案
好.知道了！当我运行sys.path时，它会先出现在".local/lib/python2.7/site-packages"中，然后再出现在"anaconda3/envs/test2/lib/python2.7/site-packages"中
Ok. Got it! When I run sys.path it looks in ".local/lib/python2.7/site-packages" before it looks in "anaconda3/envs/test2/lib/python2.7/site-packages"
我认为我从未在.local中使用python版本，因此我只是将python2.7目录移出了〜/.local/lib.这似乎可以解决该问题.现在，当我导入numpy时，版本是预期的.
I don't think I was ever using the python version in .local, and so I just moved the python2.7 directory out of ~/.local/lib. This seemed to remedy the problem. Now when I import numpy, the version is as expected.
参考: 下面的讨论以及Uvar和MSeifert的评论，为我指明了解决此问题的方向.
