Since you are on Ubuntu, could you try installing fftw via apt-get? I think the package names are libfftw3-3 and libfftw3-dev, but it might find them if you just try fftw3.
I can look further at what the package name is when I'm actually in front of a computer if none of those work :-).
@gpleiss I think I've run in to this issue, I'm not actually totally convinced that installing fftw from conda works every time.

I can't reproduce this error. Here's the steps I've taken on MacOS (w/o CUDA):
# Create a new environment
conda create --name test_env
source activate test_env
conda install ipython
source activate test_env
# Install the base libraries - based on the README instructions
conda install fftw cffi pytorch torchvision -c conda-forge -c pytorch
git clone https://github.com/cornellius-gp/gpytorch.git ~/workspace/gpytorch
cd ~/workspace/gpytorch
python setup.py installThen, when I'm working in another directory, in an ipython shell
import gpytorch # Works!from gpytorch.

Problem solved after installing libfftw3-3 and libfftw3-dev. But I used aptdcon instead of apt-get as I'm on university desktop.
Thanks for the suggestion!

@imsrgadich I think we've solved the issue more generally, but it seems that you've already got a good workaround :)

I get the same error on MacOS as well.

@imsrgadich can you print the macos error? Were you using the latest version of master? And did you install fftw using anaconda? conda install fftw -c conda-forge?

Hi, I will try to reproduce the error and post it here.
Can you tell me how to get rid of this error
ImportError: No module named 'gpytorch.libfft._libfft'
This is after adding libraries = ['fftw3','fftw3f'] (from issue #20) to build.py and built it using python setup.py build. I tried reinstalling everything using the aforementioned process but in vain. Any help is apprecaited.
Full error below.

Did you try conda install fftw -c conda-forge?

Worked on Ubuntu (with CUDA) but no luck on MacOS (w/o CUDA).

There are few things I'm not able to understand. When I run python setup.py build the build files are created and stored in /build/. This creates two directories lib.linux-x86_64-3.5 and temp.linux-x86_64-3.5. The latter directory has gpytorch.libfft._libfft.o which the python code is searching in /gpytorch/libfft/ which is empty. Is there something the build process is missing? or I missed something. I moved the object file to /gpytorch/libfft/ and the issue solved. Thanks.
