@block98k can you run ```ldd``` on your libcaffe2_gpu.so and look for CUDA libs in the output? When I run this I get ``` ldd /opt/conda/lib/libcaffe2_gpu.so | grep libcu libcuda.so.1 =>...

@fierarufmihai can you manually install the same protobuf used during installation? I think the command is ```conda install -y protobuf=3.5.1.1=py27_0 -c conda-forge```

This looks like some sort of python mismatch to me. Python changed how it handled unicode and strings dramatically from python 2 to python 3, and many python errors that...

@GuoLiuFang Can you run all the commands in my previous comment?

@GuoLiuFang @Tamoghna-Saha Can you please run these commands? which python python --version echo $PYTHONPATH echo $PATH echo $LD_LIBRARY_PATH I think I will be able to help you if you give...

@Tamoghna-Saha your default python is in /usr/bin, but you built Caffe2 with the python in /usr/local/ . Can you try this running /usr/local/bin/python (might be /usr/local/bin/python2 or /usr/local/bin/python2.7) and running...

Thanks for discovering this for us. I didn't realize that the CuDNN version had to match exactly. I'll add a note about this. Did you build from source (```conda build...

I've seen a few people report this error message, but I've never been able to repro it myself so I can't say for certain. Do you know if your GPU...

Can you give your lmdb and protobuf versions? As well as PYTHONPATH and LD_LIBRARY_PATH ? It seems like you're not using Anaconda, are you using virtualenv or virtualenvwrapper?

@henryguyu does the file `/usr/local/lib/libcaffe2.so` and the directory `/usr/local/lib/python2.7/site-packages/caffe2` both exist? Is `which python` /usr/bin/python or /usr/local/bin/python? Your PYTHONPATH should not have two colons `:` in a row, and shouldn't...
