Invalid device function about mc-cnn HOT 6 OPEN

hi, I'm with the same problem, have you found a solution?
tks.

from mc-cnn.

any luck on this issue? I have the same.

from mc-cnn.

Not yet. I'm trying to reproduce some results of the Kitti Vision Benchmark (http://www.cvlibs.net/datasets/kitti/eval_scene_flow.php?benchmark=stereo) and I'm having this same 'invalid device function' error in two methods: MC-CNN-acrt (the same error of ranjeethks) and in L-ResMatch.

In L-ResMatch when I run:

scripts/preprocess_kitti.lua -color rgb -storage storage

I have the error:

luajit: scripts/preprocess_kitti.lua:113: invalid device function
stack traceback:
[C]: in function 'remove_nonvisible'
scripts/preprocess_kitti.lua:113: in main chunk
[C]: at 0x00405d50

I think my problem is memory and/or version. How should we know about which CUDA/Torch version he used in this code?

I solved my problem. Actually, since I use a cluster, I was not submitting my job to the cluster. That's why I got this problem.

from mc-cnn.

I solved my problem too.

The problem was that I had not set the correct CUDA Compute Capability according to my GPU on the Makefiles of both projects.

My GPU is a Quadro K1100M, that has CUDA Compute Capability 3.0. So, I had to change on the Makefiles of my projects the parameter sm_35 to sm_30 (sm_35 means cuda compute capability 3.5 and so on).

A table of Cuda Compute Capability of the GPUs can be found here:
https://developer.nvidia.com/cuda-gpus

Just to be more precise, I changed the following lines on the Makefile of the projects:

---------- In L-ResMatch project:

libadcensus.so: src/adcensus.cu
$(CUDA)/bin/nvcc -arch sm_35 -O3 -DNDEBUG --compiler-options '-fPIC' -o libadcensus.so --shared src/adcensus.cu $(CFLAGS) $(LDFLAGS_NVCC)

libcuresmatch.so: src/curesmatch.cu
$(CUDA)/bin/nvcc -arch sm_35 -O3 -DNDEBUG --compiler-options '-fPIC' -o libcuresmatch.so --shared src/curesmatch.cu $(CFLAGS) $(LDFLAGS_NVCC)

---------- In MC-CNN-acrt project:

libadcensus.so: adcensus.cu SpatialLogSoftMax.cu
nvcc -arch sm_35 -O3 -DNDEBUG --compiler-options '-fPIC' -o libadcensus.so --shared adcensus.cu $(CFLAGS) $(LDFLAGS_NVCC)

Just change the sm_xx to the correct one based on your videocard.
After that, it worked perfectly. (I used Cuda 8 to reproduce the code)
