问题
I'm trying to create an LMDB data base file in Python to be used with Caffe according to this tutorial. The commands import numpy as np
and import caffe
run perfectly fine. However, when I try to run import lmdb
and import deepdish as dd
, I'm getting the following errors:
>>> import lmdb
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named lmdb
>>> import deepdish as dd
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named deepdish
I'm running Python 2.7.9 through Anaconda 2.2.0 (64-bit) on Ubuntu 14.04. While installing the dependencies for Caffe according to this page, I've already installed the lmdb package through sudo apt-get install liblmdb-dev
.
Any ideas why this error might be occuring?
回答1:
Well, the apt-get install liblmdb-dev
might work with bash (in the terminal) but apparently it doesn't work with Anaconda Python. I figured Anaconda Python might require it's own module for lmdb and I followed this link. The Python installation for lmdb module can be performed by running the command pip install lmdb
in the terminal. And then import lmdb
in Python works like a charm!
The above installation commands may require sudo.

If you're using Anaconda, then this can solve your problem (it worked for me):
conda install -c https://conda.binstar.org/dougal lmdb
回答3:
For Anaconda users, installing python-lmdb
package from conda-forge
should fix the lmdb
import error:
conda install -c conda-forge python-lmdb
This was tested on conda 4.5.11
on an lxc
-containerized system running Ubuntu 18.04
.
Note that there is a conda
package named lmdb
(without python-
), installable via:
conda install -c conda-forge lmdb
that does not fix the import error.
