I run the training, run_nstep_dqn.sh of s2v_mvc and got this error: File "main.py", line 77, in <module> api = MvcLib(sys.argv) File "/home/abcd/S2V-DQN/code/s2v_mvc/mvc_lib/mvc_lib.py", line 11, in __init__ self.lib = ctypes.CDLL('%s/build/dll/libmvc.so' % dir_path) File "/home/abcd/anaconda2/envs/tensorflow-gpu/lib/python2.7/ctypes/__init__.py", line 366, in __init__ self._handle = _dlopen(self._name, mode) OSError: /home/abcd/S2V-DQN/code/s2v_mvc/mvc_lib/build/dll/libmvc.so: undefined symbol: _ZTVN3fmt11FormatErrorE

Hi, you need to compile with position independent mode of libfmt.

Then recompile and reinstall limfmt
