配置anaconda環(huán)境（linux）

安裝Anaconda

1.下載
wget https://repo.anaconda.com/archive/Anaconda3-5.0.1-Linux-x86_64.sh

  1. 安裝

在安裝包路徑下執(zhí)行：
bash Anaconda3-5.0.1-Linux-x86_64.sh

安裝過程中會需要不斷回車來閱讀并同意license。

安裝路徑默認(rèn)為用戶目錄(可以自己指定)，最后需要確認(rèn)將路徑加入用戶的.bashrc中。

  1. 編輯.bashrc文件

打開文件
vi ~/.bashrc # 編輯 .bashrc

在最后一行加入：
export PATH="$PATH:~/anaconda3/bin"
保存

最后，立即使路徑生效，需要在用戶目錄下執(zhí)行：（一定不要忘了執(zhí)行）
source ~/.bashrc

  1. 查看conda環(huán)境列表
    conda info --envs

安裝 Astropy 和 IRAF

步驟

換源

  • conda添加源
# 附更換清華鏡像源的方式：
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --set show_channel_urls yes

# 附加庫：
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/menpo/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/

conda config --add channels http://ssb.stsci.edu/astroconda
  • 查看源
    conda config --show
  • 刪除源
conda config --remove channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
conda config --remove-key channels # 刪除所有源

設(shè)置環(huán)境變量

Cl>set terminal=vt100

一些報錯的解決方式

1.conda install 時出錯： CondaError: Downloaded bytes did not match Content-Length

  • 方法一
    換源

  • 方法二
    設(shè)置conda下載的timeout，然后再進(jìn)行嘗試，如果時長不夠可以再設(shè)置大一點(diǎn)。
    conda config --set remote_read_timeout_secs 600.0
    然后運(yùn)行安裝命令
    conda install 包 即可。

  • 方法三
    從conda的源下載好要安裝的包，直接采用本地安裝的方式。下載的url再出錯的地方有提示：
    url: http://ssb.stsci.edu/astroconda/linux-64/iraf-2.16.UR.1-0.tar.bz2
    離線安裝：
    conda install --offline ./iraf-2.16.UR.1-0.tar.bz2

  1. 啟動iraf時輸入cl報錯：/usr/local/bin/rar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

原因：64位系統(tǒng)中安裝了32位程序
解決方法：
yum install glibc.i686

重新安裝以后還有如下類系錯誤 再繼續(xù)安裝包
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
yum install libstdc++.so.6

conda安裝ds9

conda install -c pkgw/label/superseded ds9

jupyter notebook配置

  • 修改jupyter_notebook_config.py
jupyter notebook --generate-config
vi /home/zy/.jupyter/jupyter_notebook_config.py

作如下修改：
c.NotebookApp.allow_root = Ture
c.NotebookApp.notebook_dir = '路徑'

  • 關(guān)聯(lián)Jupyter Notebook和conda的環(huán)境和包——“nb_conda”
    conda install nb_conda
