Hello YT-community,

I have been trying to use yt for analysis of the output from a GADGET 2 simulation stored as an Unformatted Fortran Binary. It consists of files named as snapshot_068 which is divided into 1024 subfiles named as snapshot_068.0, snapshot_068.1 and so on. Whenever I am loading this with yt I am getting the following error message and I have got no idea as to how to fix this. I have also tried reading only one subfile of this multi part snapshot but with no success. I am relying on the community to help me in this regard.

My code:

fname = 'snapdir_068/snapshot_068'
ds = yt.load(fname)

Error displayed:

yt : [ERROR    ] 2017-02-22 21:55:34,587 None of the arguments provided to load() is a valid file
yt : [ERROR    ] 2017-02-22 21:55:34,587 Please check that you have used a correct path

#Trying to read only one of the multi part file

My code:

fname = 'snapdir_068/snapshot_068.0'
ds = yt.load(fname)

Error displayed:
