实验室linux服务器安装gym出现的问题

1.1 conda install gym[all]

出现错误：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

之前只有清华源，后来加了阿里云和中科大，同样还是找不到gym包

1.2 直接从anaconda下载

该文章提出三种解决方法：
第二种：conda install -c conda-forge gym-all
得到同样的错误

第三种直接从anaconda下载，再进行安装，根据环境(linux-64, python=3.8.3)选择安装包

测试gym

conda list

import gym
env = gym.make('CartPole-v1')
for i_episode in range(20):observation = env.reset()for t in range(100):env.render()print(observation)action = env.action_space.sample()observation, reward, done, info = env.step(action)if done:print("Episode finished after {} timesteps".format(t+1))break

出现错误：

Traceback (most recent call last):File "test.py", line 2, in <module>env = gym.make('CartPole-v1')
AttributeError: module 'gym' has no attribute 'make'

1.3 AttributeError: module ‘gym’ has no attribute ‘make’

这是因为我把git下载的Gym文件夹和test.py放一个目录下，当我移除gym文件夹后，gym模块便不存在了

(zhu_pytorch) [new402@~]$python zhu_xw/test.py
Traceback (most recent call last):File "zhu_xw/test.py", line 1, in <module>import gym
ModuleNotFoundError: No module named 'gym'

2. pip install gym[all]

ERROR: Could not find a version that satisfies the requirement gym[all] (from versions: none)
ERROR: No matching distribution found for gym[all]

.html
该文章提出了将Git下载的gym文件夹复制到linux中再安装

git clone .git
#进入 gym 文件夹：
cd gym
pip install -e .[all]

出现错误

ERROR: Command errored out with exit status 1:command: /home/new402/anaconda3/envs/zhu_pytorch/bin/python /home/new402/anaconda3/envs/zhu_pytorch/lib/python3.8/site-packages/pip install --ignore-installed --no-user --prefix /tmp/pip-build-env-vx48f_zn/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i 'https：//pypi.tuna.tsinghua.edu/simple/' --trusted-host pypi.douban -- 'setuptools>=40.8.0' wheelcwd: None

简中并没有解决这个问题的帖子，类似问题的解决方法也解决不了。

2.1 安装依赖项

参考文章：

sudo apt-get install -y cmake zlib1g-dev libjpeg-dev xvfb xorg-dev python-opengl libboost-all-dev libsdl2-dev swig

出现错误：

Package cmake is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

跟1.1同样的缺包问题

参考：.html

解决方法如下：
# apt-get update
# apt-get upgrade
# apt-get install <packagename>
这样就可以正常使用apt-get了～

出现错误

$apt-get update

缺包问题另一篇文章提出不同看法()

表示这个问题的原因是ubuntu的/etc/apt/source.list中的源比较旧了，需要更新一下，更新方法：

sudo apt-get update

2.1.1 更新源

参考：

第一步，在官网源，我的版本是9.4.0

cat /proc/versionLinux version 5.15.0-48-generic (buildd@lcy02-amd64-043) (gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.   0, GNU ld (GNU Binutils for Ubuntu) 2.34) 

实验室给的服务器版本太老了，连网页都给出警告

第二步，用vim替换原有的source.list的内容

sudo vim /etc/apt/sources.list

第三步，更新：sudo apt-get update，仍然有错误

2.2 安装mujoco

参考文章：

cd ~
mkdir .mujoco
wget .zip
unzip mjpro150_linux.zip

在第三步下载出错：

ERROR: cannot verify www.roboti.us's certificate, issued by ‘C=CN,O=Doctorcom LTD.,CN=demotest.doctorcom’:Self-signed certificate encountered.ERROR: certificate common name ‘demotest.doctorcom’ doesn't match requested host name ‘www.roboti.us’.
To connect to www.roboti.us insecurely, use `--no-check-certificate'.

于是直接下载到windows解压再复制到服务器里，放在.mujoco下

把如下内容添加到 .bashrc 文件中（参考）

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/.mujoco/mjpro150/bin:/usr/local/cuda-10.2/lib64
export MUJOCO_KEY_PATH=~/.mujoco:~/.mujoco/mjpro150/bin:$MUJOCO_KEY_PATH

验证一下安装的正确性

cd ~/.mujoco/mjpro150/bin
./simulate

报错

[new402@~/.mujoco/mjpro150/bin]$./simulate
./simulate: error while loading shared libraries: libmujoco150.so: cannot open shared object file: No such file or directory

需source ~/.bashrc使.bashrc 文件生效再验证

2.2.1 安装mujoco-py

下载好对应的150版本的文件

wget .50.1.0.tar.gz

按照GitHub上说的，安装好必备的一些包

sudo apt install libosmesa6-dev libgl1-mesa-glx libglfw3

出现错误
