The tutorial for larcv is not working.

So since i cannot find any other documentation than (this)[http://deeplearnphysics.org/Blog/2018-01-01-BrowsingSegmentationData_v0.1.0.html] im trying to reproduce steps from the notebook to read the data.

the step:

    # Let's grab a specific projection (1st one)
    image2d = larcv.as_ndarray(chain_image2d.image2d_data_branch.as_vector().front())
    label2d = larcv.as_ndarray(chain_label2d.image2d_segment_branch.as_vector().front())

I yielding following error:

TypeError                                 Traceback (most recent call last)
<ipython-input-25-538f91b3987a> in <module>
     48 # Let's look at one specific event entry
     49 ENTRY = 2
---> 50 image2d, label2d = show_event(ENTRY)

<ipython-input-25-538f91b3987a> in show_event(entry)
     26 
     27     # Let's grab a specific projection (1st one)
---> 28     image2d = larcv.as_ndarray(chain_image2d.image2d_data_branch.as_vector().front())
     29     label2d = larcv.as_ndarray(chain_label2d.image2d_segment_branch.as_vector().front())
     30 

TypeError: requested class 'larcv' does not exist

Which can be reduced a little bit to the following print:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-27-88206382776f> in <module>
     49 # Let's look at one specific event entry
     50 ENTRY = 2
---> 51 image2d, label2d = show_event(ENTRY)

<ipython-input-27-88206382776f> in show_event(entry)
     25     chain_image2d.GetEntry(entry)
     26 
---> 27     print(chain_image2d.image2d_data_branch)
     28     # Let's grab a specific projection (1st one)
     29     image2d = larcv.as_ndarray(chain_image2d.image2d_data_branch.as_vector().front())

TypeError: requested class 'larcv' does not exist

And it seems to be because of some wrong API.
