I installed the lmdb as this link (https://lmdb.readthedocs.org/en/release/). Then I have the error: 

               " ImportError: No module named caffe" 

I read the link (https://github.com/BVLC/caffe/issues/263) ,but I still don't know how to set the " PATHONPATH " in ubuntu 14.04.

Who can help me?

Has anyone been able to address this issue yet? I'm trying to create a LMDB data base according to this tutorial. In python environment, "import caffe" runs fine. However, when I try to run "import lmdb" I'm getting the folllowing error:

>>> import lmdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named lmdb

Have u fixed it? How?

[Wei Yang]

for Anaconda python, try

pip install lmdb

otherwise try

sudo apt-get install liblmdv-dev

even after doing pip install lmdb I am getting the same error.
What should I do next?

This may not be helpful as I know that this thread is old, but I encountered an similar error, and I *needed* to pip install lmdb, even after installing it apt-get install liblmdb-dev. If this method isn't working for you, double check that your caffe python interpreter, default terminal python interpreter (i.e. if you run pip in the terminal), and your IDE interpreter are all the same. You could be installing lmdb with one and then testing with another.

Hi Jonathan Balloch,

Those two commands solved the issue for me

pip install lmdb,
apt-get install liblmdb-dev

Thanks
