Error: expected an indented block

Can someone explain why I am getting this error? 

from netCDF4 import Dataset
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap

datapath = r"C:\Users\matth\Downloads\MYD04_L2_v6.0_110E155E_045S010S.A2010_calcv2_dod_flg1.nc"
f = Dataset(datapath)

for i in range(0, 30):
    dod = f.variables['dod_modis_flg1'][i]
    dod[dod == 0] = np.nan

    def nan_if(arr, value):
        return np.where(arr == value, np.nan, arr)
    mean = np.nanmean([nan_if(dod, -9.99)])
    print(mean)
    #print(np.nanmax(dod))
    #print(np.nanmin([nan_if(dod, -9.99)]))

    dod_high = dod[(dod > mean) & (dod != 0)]
    anomalies = []
    for val in dod_high:
        if val > mean:
            #print(anomalies)

    dod_high_indices1 = np.where((dod > mean) & (dod != 0))
    dod_high_indices2 = np.array(np.where((dod > mean) & (dod != 0))).T
    anomalies_ind = []
    for ind in dod_high_indices2:
        anomalies_ind.append(ind)
        print(np.asarray(anomalies_ind))

OUTPUT: 

%run "C:/Users/matth/dod_anomalies.py"
  File "C:\Users\matth\dod_anomalies.py", line 26
   dod_high_indices1 = np.where((dod > mean) & (dod != 0))

IndentationError: expected an indented block

It seems to me that the indentation of my code is correct... for some reason, I keep on getting this error.

Python is expecting something after 

if val > mean:

It ignores the commented block. If you have an empty if statement like that, just put in pass, so python knows that it is there.

if val>mean:
    #print(anomalies)
    pass

An if needs a body, and in

for val in dod_high:
    if val > mean:
        #print(anomalies)

a comment doesn't count. You could make the body pass, or comment out the if (or the whole loop), but in context, it seems like you might have more serious problems. Even uncommented, that print would only ever have printed [].
