Error about calculating lifted_index

[ShareRingNS]

lindex=np.zeros((151,151))
for i in range(151):
    for j in range(151):

        parcel_profile=((mpcalc.parcel_profile(units.Quantity([900.,500.],'hPa'), t_900[i,j], dew_900[i,j])))

        lindex = mpcalc.lifted_index(units.Quantity([500.],'hPa'), t_2[i,j], parcel_profile)
        print(lindex)

t_ 900 (1 * 151 * 151, temperature value at 900hpa on each gird ), dew_ 900 (1 * 151 * 151, dew value at 900hpa on each gird ).
I noticed that parcel_ profile returns multiple values. Should I select one of them? I'm sorry I'm a beginner in the field of atmosphere, and I don't know much about this field.

Sorry this got lost. parcel_profile returns one temperature value for each of the pressure values given to it. The challenge for your case is that it only currently functions on a single parcel, it won't work properly on your grid of values.
