Question

我有不同的蟒蛇环境。启动其中之一时，似乎sys.path仍设置为完全错误的目录。我不是正确地理解了环境的概念，或者这是与我的蟒蛇设置有关的错误？

我的环境：

fabianwerner ~$ conda env list
# conda environments:
#
base                  *  /Users/fabianwerner/anaconda3/anaconda3
my-rdkit-env             /Users/fabianwerner/anaconda3/anaconda3/envs/my-rdkit-env
openpose                 /Users/fabianwerner/anaconda3/anaconda3/envs/openpose

fabianwerner ~$

我激活环境“ openpose”：

fabianwerner ~$ conda activate openpose
(openpose) fabianwerner ~$

我将尝试导入“ keras”，因此让我们确保已安装它：

(openpose) fabianwerner ~$ pip list | grep -i keras
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
Keras (2.2.4)
Keras-Applications (1.0.7)
Keras-Preprocessing (1.0.9)
You are using pip version 9.0.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
(openpose) fabianwerner ~$

我启动python并尝试导入keras：

(openpose) fabianwerner ~$ python
Python 3.6.5 |Anaconda, Inc.| (default, Apr 26 2018, 08:42:37) 
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import keras
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'keras'
>>>

让我们检查python在哪里寻找模块：

>>> import sys
>>> print(sys.path)   
['', '/Users/fabianwerner/anaconda3/anaconda3/envs/my-rdkit-env/lib/python36.zip', '/Users/fabianwerner/anaconda3/anaconda3/envs/my-rdkit-env/lib/python3.6', '/Users/fabianwerner/anaconda3/anaconda3/envs/my-rdkit-env/lib/python3.6/lib-dynload', '/Users/fabianwerner/.local/lib/python3.6/site-packages', '/Users/fabianwerner/anaconda3/anaconda3/envs/my-rdkit-env/lib/python3.6/site-packages']
>>>

所以我激活了环境'openpose'，但是它仍然在另一个（错误的）环境'my-rdkit-env'中寻找模块！

该如何解决？

编辑：

我无法看到anaconda设置的任何明显问题，因为conda info -a提供了正确的路径：

(openpose) fabianwerner ~$ conda info -a

此外，我似乎没有设置与python相关的环境变量：

(openpose) fabianwerner ~$ printenv | grep -i python
CONDA_PYTHON_EXE=/Users/fabianwerner/anaconda3/anaconda3/bin/python
(openpose) fabianwerner ~$

我的设置：

Mac OS-X 10.13.6（High Sierra）
anaconda版本4.5.11

谢谢

您在示例中启动的Python解释器不是环境中的那个。 conda info -a说python version : 3.7.0.final.0，而您的口译员说Python 3.6.5

当您激活环境并运行which python时，问题应该变得很明显，该环境应该指向已激活的环境，但可能并非如此。

您是如何创建这些环境的？确保设置python=XX选项，否则新环境将使用基础/根环境中的解释器，而不是安装新的解释器。即conda create -n my_environment python=3.7

编辑：抱歉，我只是抬起头来并测试了conda info -a。 python version : XX似乎是指基本环境，而不是当前活动的环境。

我在这里留下这个答案，因为即使我的推理似乎是错误的，它仍然可能会有所帮助。

Anaconda选择正确的环境但是错误的sys.path？
