I have installed caffe-ssd with OpenCV version 3.2.0, CUDA version 9.2.148 and CuDNN version 7.2.1.38.

These are my settings in Makefile.config

# cuDNN acceleration switch (uncomment to build with cuDNN).
USE_CUDNN := 1

# CPU-only switch (uncomment to build without GPU support).
# CPU_ONLY := 1

# Uncomment if you're using OpenCV 3
OPENCV_VERSION := 3

# We need to be able to find Python.h and numpy/arrayobject.h.
PYTHON_INCLUDE := /usr/include/python2.7 \
        /usr/local/lib/python2.7/dist-packages/numpy/core/include

# Uncomment to support layers written in Python (will link against    Python libs)
WITH_PYTHON_LAYER := 1

# Whatever else you find you need goes here.
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial/

All tests were passed.

[----------] Global test environment tear-down
[==========] 1266 tests from 168 test cases ran. (45001 ms total)
[  PASSED  ] 1266 tests.

Thereafter I follow this link for SSD. The LMDB creation works without a problem but when I run 

python examples/ssd/ssd_pascal.py

I get the following error

I0820 14:16:29.089138 22429 caffe.cpp:217] Using GPUs 0

I have an NVIDIA GeForce GTX 1080 Ti graphics card.

I've tried compiling a simple Cuda code with nvcc and run it without any problem. I'm able to import caffe without any issue.

I have checked this question and that's not my problem.

    is it possible that your `Makefile.config` is changed when you install SSD on top of caffe? can you run `make test` after installing SSD? – Shai Aug 20 '18 at 12:55

    Seems you're right. But now I'm getting "error == cudaSuccess (7 vs. 0) too many resources requested for launch" – Harsh Wardhan Aug 21 '18 at 06:35
  • is it possible other processes are also using your GPU? – Shai Aug 21 '18 at 06:42
  • I have checked. No other process is running. I'm able to run the regular Caffe on the GPU without any problem. – Harsh Wardhan Aug 23 '18 at 14:00
  • Unless you've changed the default parameters, SSD by default uses VGG backbone with batch size of 10 images. Could you try to reduce the batch size? – rkellerm Aug 30 '18 at 08:53

for the error error == cudaSuccess (7 vs. 0)

change from gpus = "0,1,2,3" to gpus = "0" in ssd_pascal.py and also check the path of cuda in CUDA_DIR in Makefile.config and update it with the proper path and version that is installed in your system.

and for error “Cannot use GPU in CPU-only Caffe” build the ssd again using make test command
