missing submodule dependency

[aapocketz]

When running the data generation script, I am missing files

source_material/gutenberg_shakespeare.txt: No such file or directory
Traceback (most recent call last):
  File "/home/aaron/src/radioml/dataset/generate_RML2016.10a.py", line 39, in <module>
    src = source_alphabet(alphabet_type, tx_len, True)
  File "/home/aaron/src/radioml/dataset/source_alphabet.py", line 13, in __init__
    self.src = blocks.file_source(gr.sizeof_char, "source_material/gutenberg_shakespeare.txt")
  File "/home/aaron/src/gr/lib/python2.7/dist-packages/gnuradio/blocks/blocks_swig0.py", line 436, in make
    return _blocks_swig0.file_source_make(*args, **kwargs)
RuntimeError: can't open file

I do not appear to have access to the dependent submodule.

$ git submodule update
Cloning into 'source_material'...
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
fatal: clone of 'git@github.com:radioML/source_material.git' into submodule path 'source_material' failed

Are these files necessary or there is a way to bypass them (use random number generator maybe?)

I was using submodules properly, I just didn't have access. Running it again worked now. Thanks!

git@github.com:radioML/source_material.git

means it's a clone with ssh. So be sure that you have entered your ssh public key in github
