I am new to Python and a I need to performe some calculations using the package Scipy.
I installed Scipy (0.14) from synaptic and implemented the desired code.
Everything worked well.
Now, I realized that I need to download a newer version of the source code (more precisely, https:// github.com/ scipy/scipy/blob/master/scipy/optimize/ slsqp.py) and modify it before performing the calculations.

How can I use the modified code without changing the installed version?

It follows a simple version of the problem I need to solve

import numpy as np
import scipy
from scipy.optimize import minimize # here I need to insert the modified code

#######################

def blackbox(x):
fit = 0
for val in x:
fit = fit + val*val

return fit


#######################


x0=[1,1]


print scipy.__version__

res = minimize(blackbox, x0, method='SLSQP', options={'disp': True, 'maxiter':10, 'eps': 0.01, 'ftol': 1e-05})

print(res.x)

A safe way would be to install a second identical python version in a different path. Then one python install would have one scipy version and the other python install would have another scipy version.

The obvious choice is to use Virtualenv intro Virtual Environments.

I wish I knew that 3 days ago, I would not have to lose all of my 3.5 stuff.
I ma going to try that and see if it works.
