#1869: Griddata: "memory leak"
----------------------------------+-----------------------------------------
Reporter: MSilva | Owner: pv
Type: defect | Status: new
Priority: normal | Milestone: Unscheduled
Component: scipy.interpolate | Version: devel
Keywords: griddata interpolate |
----------------------------------+-----------------------------------------
Runing griddata inside a loop makes the memory usage increase without
bound.
Example (from example in the official documentation):
def func(x, y):
return x*(1-x)*np.cos(4*np.pi*x) * np.sin(4*np.pi*y**2)**2
grid_x, grid_y = np.mgrid[0:1:100j, 0:1:200j]
points = np.random.rand(1000, 2)
values = func(points[:,0], points[:,1])
for i in range(100000):
grid_z1 = griddata(points, values, (grid_x, grid_y), method='linear')
