after I exit the expresso and restart again, it reports:ImportError: No module named Image about expresso

Image is a part of python PIL library only. First of all, remove existing PIL library. Then, Try following these commands, and see if it works -

sudo apt-get install python-imaging

If it doesn't work try installing these dependencies too . . .
sudo apt-get install libjpeg libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev

issue might be, related to path and dependency settings in pip. These issues came up for scipy too, which was resolved by using sudo apt-get rather than pip for the installations . . .

I try your advice, but still not work yet
however, I changed the the $PATH from

echo $PATH
/home/ubgpu/anaconda3/bin:/home/ubgpu/anaconda/bin:/usr/local/cuda/bin:/home/ubgpu/torch/install/bin:/home/ubgpu/torch/install/bin:/srv/spark/bin:/usr/local/cuda/bin:/home/ubgpu/torch/install/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/ubgpu/dev/npm/bin

to

ubgpu@ubgpu:/source_for_caffe/1/expresso$ echo $PATH
/home/ubgpu/torch/install/bin:/home/ubgpu/torch/install/bin:/srv/spark/bin:/usr/local/cuda/bin:/home/ubgpu/torch/install/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/ubgpu/dev/npm/bin
ubgpu@ubgpu:/source_for_caffe/1/expresso$

and it works!
