GhPythonRemote - Scipy module object has no attribute 'optimize'

Greetings everyone.

I am trying to use the scipy.optimize.minimize func inside GH using the Remote component but it fails. Here’s the python code for quick reference . The problem that I can’t seem to figure out is how can the matplotlib.pyplot module work but when i attempt to load the scipy.optimize module it doesn’t work? How can I make it work? I have used the conda install scipy in the rhinoremote environment as well as the

ghpyremote_import_scipy_module_error.gh (16.7 KB)

import scriptcontext 
import rhinoscriptsyntax as rs

np = scriptcontext.sticky['numpy']
mpl = scriptcontext.sticky['matplotlib']
plt = mpl.pyplot #How come the pyplot extension is succesfully imported but scipy isnt

arr = np.linspace(-1,1,25)
plt.plot(-arr, np.sin(arr), c = 'r')
plt.plot(np.tan(arr), -arr[::-1], c='orange')
plt.show()

#scipy import
scipy = scriptcontext.sticky['scipy']
_minimize = scipy.optimize.minimize

#Objective function
s = 20000
l = 40000
def objective(arr):
    x = arr[0]
    y = arr[1]
    w = arr[2]
    o = arr[3]
    return (o - w / 2) % x + (s - w) % x + (l - y - (o + (l-s)//s*s + w / 2)) % x
initial = [1500, 600, 1600, 6000]
bounds = [(1500,2100), (600, 2350),(1600,2600), (3000,15000)]
sol = _minimize(fun=objective, x0=initial, bounds=bounds, method='Nelder-Mead')

And Here is the error I get

Runtime error (Exception): 'module' object has no attribute 'optimize'

You need one import name per submodule you want to use, and it’s a good idea to import the higher-level modules first.

So in the modules input to GHPythonRemote, add scipy.optimize at the bottom of the list and you should be good to go. To use integrate in your GHPython scripts, you will need something like optimize = scriptcontext.sticky['scipy.optimize'].

It worked! Many thanks. The solution was just under my nose.
