OpenCv Setup on Ubuntu

Question

Hi I am trying to setup OpenCV Licence Plate Detection System on Ubuntu 16.

I used this for OpenCV installation sudo apt-get install libopencv-dev python-opencv

When I am trying to run the script with python I am getting this

libdc1394 error: Failed to initialize libdc1394
Traceback (most recent call last):
  File "Main.py", line 7, in <module>
    import DetectChars
  File "/home/tushar/OpenCV_3_License_Plate_Recognition_Python-master/DetectChars.py", line 14, in <module>
    kNearest = cv2.ml.KNearest_create()
AttributeError: 'module' object has no attribute 'ml'

The same Script is working fine on windows installation of OpenCV and Python2.

I am using This Repository

Please Help me with this Thanks in Advance.

I suggest you to install Anaconda: https://www.continuum.io/downloads And install opencv3: conda install scikit-image opencv

I guess you have installed OpenCV 2 instead of OpenCV 3 (ml does not exist in OpenCV version 2)

According to http://milq.github.io/install-opencv-ubuntu-debian/

sudo apt-get install libopencv-dev python-opencv

installs openCV from Ubuntu repository and may not install the latest openCV.

You can check you OpenCV version with

In [1]: import cv2

In [2]: cv2.__version__

You should then follow OPTION 2 from the above tutorial because you seem to have a subversion of opencv 2.

Hi actually i have already tried option 2 but the result is still the same.

Did you remove correctly the previous installation ?
