Question

我成功安装了rllab：

$ source activate rllab3
(rllab3) $ Python 3.5.2 :: Continuum Analytics, Inc.
(rllab3)  $ import rllab
(rllab3)  $

但是当我尝试导入其他库时：

(rllab3) $ from rllab.algos.trpo import TRPO
 from: can't read /var/mail/rllab.algos.trpo

 (rllab3) $ from rllab import rllab
 from: can't read /var/mail/rllab

我能理解为什么会这样。我定义了环境变量

export PYTHONPATH="${PYTHONPATH}:/home/b**/rllab3"

当我尝试从spyder加载它时：

[] import rllab
Traceback (most recent call last):
File "<ipython-input-1-6bfd29d10263>", line 1, in <module>
import rllab
ModuleNotFoundError: No module named 'rllab'

我无法解决问题。如果问题是环境变量，有人可以帮我解决吗？我找不到我的系统上安装了rllab的地方（我用anaconda安装了它）

Answer 1

我知道这个帖子很老了，但我最近开始研究rllab，这是我的理解。 rllab3是类似于虚拟环境的conda环境，如rllab documentation中所述。它没有安装实际的模块，你需要单独安装它。

(rllab3) $ python3
Python 3.5.2 |Continuum Analytics, Inc.| (default, Jul  2 2016, 17:52:12)
[GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)] on darwin

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

要使用该软件包，您需要下载实际的软件包，并指向该软件包的python路径。

(rllab3) $ pwd
/Users/r**/***/repo/rllab
(rllab3) $ python3
