Question

我正在尝试在没有Internet的远程计算机上安装custom OpenAI gym environment。

我将所有文件从主节点传输到远程计算机。

然后尝试如下安装健身房环境：

(tf-gpu) [username@localhost gym-CartPole-bt-v0]$ pip install -e .
Obtaining file:///home/username/code/openai/gym-CartPole-bt-v0
Requirement already satisfied: gym in /home/username/miniconda3/envs/tf-gpu/lib/python3.7/site-packages (from gym-CartPole-BT==0.0.1) (0.16.0)
Requirement already satisfied: pyglet<=1.5.0,>=1.4.0 in /home/username/miniconda3/envs/tf-gpu/lib/python3.7/site-packages (from gym->gym-CartPole-BT==0.0.1) (1.4.10)

...

ERROR: Could not find a version that satisfies the requirement cloudpickle~=1.2.0 (from gym->gym-CartPole-BT==0.0.1) (from versions: none)
ERROR: No matching distribution found for cloudpickle~=1.2.0 (from gym->gym-CartPole-BT==0.0.1)

我不确定在此过程中到底是什么问题或为什么它需要访问互联网。

但是我确实进行了检查，并且安装了更新版本的cloudpickle：

$ conda list
# packages in environment at /home/username/miniconda3/envs/tf-gpu:
#
# Name                    Version                   Build  Channel
...
cloudpickle               1.3.0                    pypi_0    pypi
...

任何人都可以解释这里发生的事情以及解决该问题的想法吗？

我回到主节点并运行以下命令，它似乎将cloudpickle版本改回了

(tf-gpu) [username@hostname gym-CartPole-bt-v0]$ pip install gym
