Hi,

I would like to use this packae but I have the following problem:

Traceback (most recent call last):
  File "/home/mwm/anaconda3/lib/python3.6/site-packages/larcv-3.0a1-py3.6-linux-x86_64.egg/larcv/larcv.py", line 14, in swig_import_helper
    return importlib.import_module(mname)
  File "/home/mwm/anaconda3/lib/python3.6/importlib/__init__.py", line 126, in import_module

During handling of the above exception, another exception occurred:

The libhdf5_cpp.so.103 actually exists and is in my python installation.

I think this is a quirk of conda: you don't actually get the library path in your environment. It looks like you could do:

export LD_LIBRARY_PATH=/home/mwm/anaconda3/lib/:$LD_LIBRARY_PATH and it might work. Is that the location of the file libhdf5_cpp.so.103? If not, add the containing folder to your ld library path and I think it will work.

@coreyjadams thanks, it actually works :D
