torchac installed but still error torchac backend not found

python -c "import torchac" gives no error
but
python l3c.py ../../L3C 0524_0001 enc ../figs out.l3c
gives error torchac_backend not found.
gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0
Are you sure you are running in the same environment? I.e. what does pip list show? Can you obtain a stacktrace by replacing the line
print('*** ERROR: torchac_backend not found. Please see README.')
in torchac/torchac.py, with
raise ImportError('*** ERROR: torchac_backend not found. Please see README.')
import torchac_backend_cpu as torchac_backend

I seem to meet the same problem.
I installed the torchac successfully(COMPILE_CUDA=auto python setup.py install).
But I can't import torchac_backend_cpu now.
I have no idea if it is just because my GCC version is 5.4(ubuntu16.04)
I have the same problem, With CUDA its working. But with CPU its not working. Someone is working on this?
Hi all. Sorry for the inconvenience -- sadly I don't have a lot of experience with compiling custom PyTorch modules :)
BUT, I think I found the problem!! It probably crept in very shortly before release, and is L36 in torchac.cpp. There, I define COMPILE_CUDA even though that should only be defined by setup.py. (The idea is that setup.py sets this to change compilation).
Anyway, please try:
- Remove this line
- Uninstall any backends you installed: (
pip uninstall torchac-backend-cpuand/orpip uninstall torchac-backend-gpu) - Recompile
Let me know if it helps!
I'm closing this for now, re-open if there are still problems.
