pg.interpolate() giving error with regionwise regularization

[Abhishek]

Python version: e.g. 3.9, 3.10, etc.?

I'm trying to extract data from mgr.paradomain and interpolating it. however it is giving error with regionwise regularization. It is working good if using simple inversion. Geometry is same as mentioned in #712 .

mgrReg = tt.TravelTimeManager(data, verbose=True)
mgrReg.setMesh(mesh)
mgrReg.inv.setRegularization(background=False)
mgrReg.fop.setRegionProperties(regionNr=1, single=True, startModel=1/6000)
mgrReg.fop.setRegionProperties(regionNr=1, startModel=1/5500.)
mgrReg.fop.setRegionProperties(regionNr=2, startModel=1/2000.)

velInvReg = mgrReg.invert(lam=10, useGradient=False, zWeight=12, secNodes=5,blockyModel = True,
                          lambdaFactor=1, cType=2, verbose=True)

x_start_cord = 0 
x_end_cord = 0.06195 
y_start_cord = 0
y_end_cord = 0
number_of_points = 100

# list of probe points for your 1D slice through the center
pntsHorz = np.linspace((x_start_cord, y_start_cord),(x_end_cord, y_end_cord),number_of_points)
pntsVert = np.linspace((y_start_cord, x_start_cord),(y_end_cord, x_end_cord),number_of_points)

velLineHorz = pg.interpolate(mgrReg.paraDomain, mgrReg.velocity, pntsHorz)
velLineVert = pg.interpolate(mgrReg.paraDomain, mgrReg.velocity, pntsVert)

Error

Not sure if this is the issue, but why do you set subsequently two different values for region 1?

mgrReg.fop.setRegionProperties(regionNr=1, single=True, startModel=1/6000)
mgrReg.fop.setRegionProperties(regionNr=1, startModel=1/5500.)

[Abhishek]

Oh that's the typo. It's only one value. mgrReg.fop.setRegionProperties(regionNr=1, single=True, startModel=1/6000)

[Thomas Günther]

Can you try1/mgr.paraModel as velocity? This is mapping the values back according to the region properties.

Its giving me error 'TypeError: unsupported operand type(s) for /: 'int' and 'method'
