我conda在bash终端中有一个使用Intel Python
Distribution解释器的环境。但是，在导入软件包时，它们是从看起来像系统默认Python的用户目录而非环境的目录中导入的。查看版本差异和包的__spec__来源pandas。

 ~  $  conda activate idp
 ~  $  which python
~/anaconda3/envs/idp/bin/python
 ~  $  python
Python 3.6.8 |Intel Corporation| (default, Mar  1 2019, 00:10:45)

ModuleSpec(name='pandas', loader=<_frozen_importlib_external.SourceFileLoader object at 0x7f509e184ba8>, origin='/home/torstein/.local/lib/python3.6/site-packages/pandas/__init__.py', submodule_search_locations=['/home/torstein/.local/lib/python3.6/site-packages/pandas'])
>>> 
 ~  $  conda list | head -n 3
# packages in environment at /home/torstein/anaconda3/envs/idp:

 ~  $  conda list | grep pandas
pandas                    0.24.1                   py36_3    intel
 ~  $  conda env list
# conda environments:

py36                     /home/torstein/anaconda3/envs/py36

使用base环境时，不会发生这种情况。包（例如pandas）是从正确的路径导入的：

 ~  $  conda deactivate
 ~  $  conda env list
# conda environments:
#
base                  *  /home/torstein/anaconda3
idp                      /home/torstein/anaconda3/envs/idp
py36                     /home/torstein/anaconda3/envs/py36

 ~  $  which python
~/anaconda3/bin/python
 ~  $  python

相关部分.bashrc（未在路径中显式设置anaconda）：

export PATH="/home/torstein/.cargo/bin:$PATH"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/intel/lib/intel64_lin:/opt/intel/compilers_and_libraries_2018.0.128/linux/mkl/lib/intel64_lin/"

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/torstein/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/home/torstein/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/home/torstein/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/home/torstein/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup

分别$PATH为base和idp环境产生这些s ：

 ~  $  echo $PATH
/home/torstein/anaconda3/bin:/home/torstein/anaconda3/condabin:/home/torstein/.cargo/bin:/home/torstein/.cargo/bin:/home/torstein/anaconda3/bin:/home/torstein/.cargo/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/torstein/.local/bin:/home/torstein/bin
 ~  $  conda activate idp
 ~  $  echo $PATH
/home/torstein/anaconda3/envs/idp/bin:/home/torstein/anaconda3/condabin:/home/torstein/.cargo/bin:/home/torstein/.cargo/bin:/home/torstein/anaconda3/bin:/home/torstein/.cargo/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/torstein/.local/bin:/home/torstein/bin

在pandas我 不 希望进口在这里，所在的位置应该是：

/home/torstein/anaconda3/envs/idp/lib/python3.6/site-packages/pandas
