Pycaffe: Error in "import caffe"

[Prasanna Date]

I'm trying to run Caffe in it's Python interface. I've already run the command make pycaffe in the caffe directory and it worked fine. Now, when I run the command import caffe in the python environment in the terminal (Ubuntu 14.04), I'm getting the following error:

    >>> import caffe
    Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     File "/home/pras/caffe/python/caffe/__init__.py", line 1, in <module>
      from .pycaffe import Net, SGDSolver
     File "/home/pras/caffe/python/caffe/pycaffe.py", line 11, in <module>
      import caffe.io
    ImportError: No module named io

I tried to search my computer for 'caffe.io' but couldn't find any file by that name. Any idea why this error is occurring and how to correct it?

try to

1) make pycaffe

2) run "export PYTHONPATH=/path/to/caffe/python:$PYTHONPATH" as the installation instructions specify

Thanks for the reply Christopher.
1. make pycaffe runs perfectly fine when run in the caffe directory. In fact, when I run it now, it says "Nothing to be done for 'pycaffe'".
2. The path already exists in PYTHONPATH. When I run the command "echo $PYTHONPATH", I get the following output:
     /home/pras/caffe/python:/path/to/caffe/python::/home/pras/caffe/python:/home/pras/caffe/python/caffe

What about the caffe.io? Why isn't "import caffe" able to find it?

[Christopher Catton]

What branch are you on? Try cleaning up PYTHONPATH to only be /home/pras/caffe/python.

[Prasanna Date]

Cleaned it up. The error still persists. Please have a look at the following:

pras@Pras-Inspiron-N5010:~$ echo $PYTHONPATH
:/home/pras/caffe/python
pras@Pras-Inspiron-N5010:~$ cd caffe
pras@Pras-Inspiron-N5010:~/caffe$ make pycaffe
make: Nothing to be done for `pycaffe'.

Did you build the project using CMake or just Make?

[Prasanna Date]

I had built it using Make.

[Christopher Catton]

I've only ever used CMake to build caffe and I would recommend you to give it a shot. Just using make may locate the pythonpath somewhere else and you may additionally have to modify the Makefile.config file.

Dear Mr.Catton.

I am new in this field. I have a same problem. 

AttributeError: module 'caffe' has no attribute 'io'.

based on http://caffe.berkeleyvision.org/tutorial/interfaces.html#python

How to compile pycaffe in anaconda or python. Thanks you in advance.
