segfault src/path_trie.cpp: No such file or directory.

Hello,

When I use language model in a binary format I get a segfault. I tried to run in gdb and it seems that path_trie.cpp is missing. What could be a problem?

Thread 24 "python" received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fff45fff700 (LWP 9951)] PathTrie::get_path_trie (this=this@entry=0x7fff45ffebe0, new_char=new_char@entry=1, new_timestep=new_timestep@entry=0, reset=reset@entry=true) at /tmp/pip-qveo70c7-build/ctcdecode/src/path_trie.cpp:56 56 /tmp/pip-qveo70c7-build/ctcdecode/src/path_trie.cpp: No such file or directory.

Hi,I've got the following information not in this project but related:
beam_args.add_argument('--lm-path', default="", type=str,
help='Path to an (optional) kenlm language model for use with beam search (req'd with trie)')
and what should the lm-path be like if i want to use the kenlm for example using"https://github.com/kpu/kenlm/tree/master/lm"?
Thank you!

Thank you!
To add,the use of lm-path is like the following:
class BeamCTCDecoder(Decoder):
def init(self, labels, lm_path=None, alpha=0, beta=0, cutoff_top_n=40, cutoff_prob=1.0, beam_width=100,
num_processes=4, blank_index=0):
super(BeamCTCDecoder, self).init(labels)
try:
from ctcdecode import CTCBeamDecoder
except ImportError:
raise ImportError("BeamCTCDecoder requires paddledecoder package.")
self._decoder = CTCBeamDecoder(labels, lm_path, alpha, beta, cutoff_top_n, cutoff_prob, beam_width,
num_processes, blank_index)
