I have 2 anaconda in my system: one with python 2.7 & and another with python 3.5.

My command prompt is showing python version as 2.7.

I need to install one package for Python 3.5 using pip only,not conda install. I installed it using pip. It's showing installed successfully, but I'm not able to import it in Anaconda with Python 3.5.

My python 2.7 path is given in path environmental variable. Can you suggest me how to install it using pip install for python 3.5?
I don't have python 3 installed in my system. I think I have anaconda 3.5 environment in my system. Please refer the screen shot. Also I can't able to install python 3.5 in my system enter image description here

To install a package in specific version, try this:

A specific version of python:

$ python-3.5 -m pip install <pkg-name>

Assuming you mean that you have two conda environments, go to a Anaconda command prompt and activate the Python 3.5 environment. Then, if pip is not installed, do:

conda install pip

Then, you should be able to run

pip install <package>

to install in to Python 3.5 provided that you are in the Python 3.5 environment.

If you don't have a Python 3.5 environment yet, simply do 

conda create --name py35 python=3.5

followed by

activate py35          (Windows)
source activate py35   (Linux or macOS)

This should be the answer for a system with Anaconda.

You can use:

pip install --install-option="--prefix=$PATH_PREFIX" <package_name>

or 

pip install -t <direct directory> <package_name>

Actually I don't have python 3.5 in my system. I think I have anaconda 3.5 environment in my system. Please refer the screen shot, I have updated in my original post & also I can't able to install python 3.5 in my system
