anaconda3部署以及使用详解

Anaconda3-2019.10-Linux-x86_64.sh

某次执行Python程序，其中两个错误信息如下：

ImportError: libcblas.so.3: cannot open shared object file: No such file or directory
Original error was: libcblas.so.3: cannot open shared object file: No such file or directory

问题：部署anaconda3卡在Unpacking payload，不能解压

[root@mcw6 ~]$ bash Anaconda3-2019.10-Linux-x86_64.sh

Anaconda3 will now be installed into this location:
/home/machangwei/anaconda3

  - Press ENTER to confirm the location
  - Press CTRL-C to abort the installation
  - Or specify a different location below

[/home/machangwei/anaconda3] >>> 
PREFIX=/home/machangwei/anaconda3
Unpacking payload ...
  0%|                                                                                                                                                     | 0/29

解决方案：之前虚拟机是1核，改成2核就可以了　　

[root@mcw6 ~]$ lscpu|grep CPU  
CPU op-mode(s):        32-bit, 64-bit
CPU(s):                2

部署anaconda3

[root@mcw6 ~]$ bash Anaconda3-2019.10-Linux-x86_64.sh
根据提示操作即可：press ENTER 或 输入 yes

Please answer 'yes' or 'no':'
>>> yes

Anaconda3 will now be installed into this location:
/home/machangwei/anaconda3

  - Press ENTER to confirm the location
  - Press CTRL-C to abort the installation
  - Or specify a different location below

[/home/machangwei/anaconda3] >>>    #这里直接按enter键，那anaconda3直接部署到命令执行的当前目录下。如果这里填写路径，
PREFIX=/root/anaconda3   #那么直接部署到填写的路径下，假设写个yes，那么直接在当前目录下创建个 yes目录，里面安装上anaconda3

conda 安装

执行安装命令之后conda install -c conda-forge prophet

就下载安装了libblas-3.9.0        | 12 KB     | #################### | 100% 

必须联网才能更新和安装新的包。跟创建虚拟环境不同，虚拟环境需要的它本身自带了，应该是这样的。

base环境执行安装命令解析环境失败，还得进Python虚拟 环境才执行安装命令成功

刚刚看错位置了，应该看这里。执行命令安装成功之后。如下，虚拟环境中增加了库文件。

总结：

1、以后研究：conda 只下载不安装，然后将包上传到离线环境conda install安装，是否支持，以后研究
2、以后验证：anaconda3 直接复制目录到其它目录或主机，添加环境变量后是否能直接使用。如果有虚拟环境，只需替换Python虚拟环境中的site-package目录。
3、conda install ，它好像是进入Python虚拟环境中执行，base中没执行成功。这样它安装了很多文件，它都安装在anaconda3目录下，应该是安装到Python虚拟环境中。可能不是安装到site-package目录下，安装模块。可能安装到Python虚拟环境的lib目录下。比如libblas.so，libblas.so.3，感觉像是系统库文件似的。

4、生产环境anaconda3缺少7个文件，都是在lib下缺少的，.so .so.3这种的。通过执行程序，查看跟生产环境一致的anaconda3的Python虚拟环境中缺少那个文件，就从正常的环境中将文件复制过去。缺谁补谁，最终成功解决问题。

5、还有很多conda命令使用，以后有时间补充

某次执行Python程序，其中两个错误信息如下：

问题：部署anaconda3卡在Unpacking payload，不能解压

解决方案：之前虚拟机是1核，改成2核就可以了

部署anaconda3
