OpenFace: `openface_server.lua` subprocess has died.

Hello I am getting the following error while trying to run openface.

Traceback (most recent call last):

Exception: 

OpenFace: `openface_server.lua` subprocess has died.

+ Is the Torch command `th` on your PATH? Check with `which th`.

+ If `th` is on your PATH, try running `./util/profile-network.lua`

  to see if Torch can correctly load and run the network.

  + If this gives illegal instruction errors, see the section on

    this in our FAQ at http://cmusatyalab.github.io/openface/faq/

  + In Docker, use a Bash login shell or source

     /root/torch/install/bin/torch-activate for the Torch environment.

+ See this GitHub issue if you are running on a non-64-bit machine:

  https://github.com/cmusatyalab/openface/issues/42

+ Advanced Users: If you think this problem is caused by

running Lua as a subprocess, Vitalius Parubochyi has created

a version of this that uses https://github.com/imodpasteur/lutorpy.

============

stdout: 

Is this error which torch ? I tried running th command in shell which shows th is properly installed.

Try running ./util/profile-network.lua as the message suggests.  I recall having this problem and the issue (If I remember correctly) was that th wasn't in the path for the program I was running.

[m.mu...@refund-suisse.ch]

I have the same problem!
In my case, OpenFace is called from apache through WSGI.

[...] torch_neural_net.py", line 161, in forwardPath

Exception:
OpenFace: `openface_server.lua` subprocess has died.

[...]

I checked the usual suspects:
- th is on PATH

- able to run ./util/profile-network.lua without issues.

- runs on a 64-bit machine

What can I do to fix this? Any idea?

[m.mu...@refund-suisse.ch]

fixed the issue by using torch_neural_net.lutorpy.py

In my python virtual environment i had to replace torch_neural_net.py with the above mentioned file.
Then remove torch_neural_net.pyc and pip install lutorpy

Please tell me how to check "th is in path"
