Take you hand-in-hand to do intensive learning experiments -- knock the level in detail

The chicken is finishing an assignment
It's hard

“ If you are not skilled in the installation environment , Don't be impatient , Calm down and breathe deeply , There will always be strange problems , Some error reports can't be read or searched , Take your time , Try to be close to my version number , Then take a snapshot ”

 The environment is as follows ：
ubuntu20.04
anaconda-5.1.0
pycharm 

0 expect

What are we going to do ？

1 Set up the environment

Download it git package , establish anaconda Environmental Science ,conda env create -f env.yml
Three files failed to download

then .condrc The document looks like this

function conda clean -i Clear index cache , Make sure you use the index provided by the mirror station .

function conda create -n myenv numpy Test it .

Still reported ssl The fault of

Still the same as before , hold .condrc Medium https Change to http, All of them ~source
Success Hahahahahaha

2 Download project

git clone https://github.com/MultiAgentLearning/playground.git Or download the compressed package directly
I didn't install git, Directly download the installation package
Then I changed my name to playground, Keep the same as the courseware

3 install

• Enter the directory of the project ,cd ~/playground
  （ Open it directly in that folder , There is no need to enter hahaha ）

• establish anaconda Environmental Science ,conda env create -f env.yml
  Here we go ！ Promise me ！ When it is executing, keep the keyboard away ！
  I tried this many times
  The source of China University of science and technology has been replaced by that of Beijing Foreign Studies University
  This time I finally saw the dawn , The download went well , Then I carefully pressed ctrl+c Then it ended , I tried many good methods and failed again
  （ Including but not limited to the following methods ：

• Direct loading gym package , pip install gym, But this is the latest version , Not the version specified in this package

• Limited version installation conda install gym==0.10.11, Still reported the same mistake

• Remove... First pommerman Environmental Science , Re execution conda env create -f env.yml, Not yet.

• Then I got my senior brother's pommerman Folder , Not yet.

• Then I changed the source , Not yet.
  ）
  When I reinstalled the environment for the second time , Didn't touch the keyboard , But still reported this error .
  steady ！

Then this time, I will keep the snapshot well , Go back to the previous state , Just execute the order again, Hahahahahaha

Finally successful hahahahahahahahaha
wuhu ！ take off ！

Then let's look at the effect

enter once ！OJBK！

4. Common commands
   Remove environment （pommerman） conda remove -n xxxx --all
   I'm stuck gym, Separate pip install gym
   Limited version installation conda install gym==0.10.11
   Take a look at the current environment env conda env list
   Activate the environment
   Out of the environment conda deactivate

Experiment

docker

perform

docker build -t pommerman/simple-agent -f examples/docker-agent/Dockerfile .
