可见此时是32位平台。
2.切换64位和32位：set CONDA_FORCE_32BIT=1是切换到32位；set CONDA_FORCE_32BIT= 是切换到64位。
需要注意的是，这样切换环境对于已经安装的python没有任何影响，即原先是64位的python，现在还是64位，所以需要切换到32位后再安装python，并且安装需要在prompt下进行，在navigator里新建的python默认是64位的。
3.安装python：conda create -n env_name python=3.6，如果需要安装一些包，只需要在name后加上对应的包名称。conda create -n env_name numpy matplotlib python=3.6。
4.切换环境：conda activate env_name，conda deactivate env_name。
5.移除环境：conda remove -n env_name --all
6.安装包：activate env_name，conda install pandas。安装anaconda发行版的所有包：conda install anaconda，但是这样会在所有环境都执行这样的操作，所以需要指定安装环境：conda install -n env_name pandas
以上的操作都是在Anaconda Prompt里，其实用Anaconda图形界面（Navigator）安装python会更加直观，但是需要注意的是，无论你是否在Prompt里设置了32位的环境，用Navigator安装的python都是64位的，大家可以试一下，有异议欢迎留言交流。
今天需要调用一个dll动态函数库，但是本地的python是64位的，dll是32位的，直接调用会报错。
OSError: [WinError 193] %1 不是有效的 Win32 应用程序。 1 python版本：3.6 anaconda对于python版本的管理还是很方便的，所以这里用anaconda才实现32位和64位python共存 1、打开anaconda prompt，输入 conda info ，可以看到现在用的是64位的。
2、切换成32位的 set CONDA_FORCE_32BIT=1 可以看出已经切换成32位的了
3、安装32位的python3.6 conda create -n python32 python=3.6
安装完成后在anaconda3文件夹下面会有一个envs文件夹
4、激活环境 conda activate python32 ，如果要取消 conda deactivate python32，如果要删除环境 conda remove -n python32--all 5、如果要在pycharm中使用该环境
