I'm trying to run the demo of py-faster-rcnn based on this GitHub page.

I have done all the previous steps. But When I try to run the demo with python ./tools/demo.py --gpu 0 --net vgg16 I get this error:

Traceback (most recent call last):
File "./tools/demo.py", line 17, in
from fast_rcnn.config import cfg
File "/home/hadi/Software/py-faster-rcnn/tools/../lib/fast_rcnn/config.py", line 23, in
from easydict import EasyDict as edict
ImportError: No module named easydict

I have installed easydict with both of these commands:

sudo pip install easydict
pip install easydict

Is this related to python path? I have installed both python 2.7 and 3.5. Since then I get all these python related errors. For example I have installed tensorflow for both python 2 and 3. But with python 2 it always says:

No module named tensorflow

How can I fix this?

OS: Ubuntu 16.04

  • what is the output of which pip? – Ravexina May 2 '17 at 9:21
  • By the way, do not send the same question at different network sites: here – Ravexina May 2 '17 at 9:22
  • You are right. Sorry about that. The output of which pip is : /usr/local/bin/pip. I think when I use pip or pip3 the modules are installed in python 3 both times. They aren't installed in python 2.7. – Hadi GhahremanNezhad May 2 '17 at 9:26
  • What is the output of: /usr/local/bin/pip --version ? – Ravexina May 2 '17 at 9:29
  • Thus is the output: pip 9.0.1 from /usr/local/lib/python3.5/dist-packages (python 3.5). When I try to install easydict, the result of both 'pip install easydict` and pip3 install easydict is : Requirement already satisfied: easydict in /usr/local/lib/python3.5/dist-packages – Hadi GhahremanNezhad May 2 '17 at 9:31

To me, it seems that you don't have pip v2 so to make sure it's installed run:

sudo apt install python-pip

It will installs pip for python v2, now lets update it:

/usr/bin/pip2 install pip --upgrade --user

After updating, run which pip2; It should give you something like:

/home/your-user-name/.local/bin/pip2

Now use pip2 to install your desired module for python2:

pip2 install easydict --user

or

/home/your-user-name/.local/bin/pip2 install easydict --user

Do not forget to change your-user-name with your username.
