DyNet: The Dynamic Neural Network Toolkit

#229 This is the CPU implementation based on Eigen SpatialConvolution. It is reported as the current fastest (available) CPU version of conv2d. For GPU support, I think implementing a new version using cublas kernels (by hand) is worthless, so I am currently incorporating cudnn into DyNet and will provide a cudnn-based (standard) implementation.

https://arxiv.org/pdf/1512.05287v5.pdf

I'm not 100% sure its correct, and it has some ugliness -- LSTMBuilder now keeps a pointer to ComputationGraph -- but Gal's dropout seems to be the preferred way to do dropout for LSTMs.

Will appreciate another pair of eyes.

With this change, DyNet can be installed with the following command line:

pip install git+https://github.com/clab/dynet#egg=dynet

If Boost is installed in a non-standard location, it has to be set in the environment variable BOOST prior to installation.

To try this out from my fork before merging the pull request, use:

pip install git+https://github.com/danielhers/dynet#egg=dynet

Hi,

We successfully implement a seq2seq model with auto-batching (in GPU) and it works great. We wanted to improve the speed by reducing the size of the softmax:

Expression W = select_rows(p2c,candsInt); Expression x = W * v; Expression candidates = log_softmax(x);

When not using auto-batching the code works and behaves as expected, however when using the auto-batch we get a runtime error what(): Magnitude of gradient is bad: inf

Thank you, Eli

Hi,

Currently I am facing problem to create a model loader in different languages(e.g. Java). Is there a better way to serialize the model (or parameters) in more human-readable way? It would be great to be more widely-used in many ways. Any kind of suggestions will be appreciated!

Thanks, YJ

Simplify Python installation process by combining the generated setup.py into the top one, using environment variables to pass information from cmake. Should allow fixing #657 now that the Cython extensions are created by the main setup.py.

I am having problem on build with BACKEND=cuda. My system is OS X (10.11.6 El Capitan) cmake works fine, once I do "make -j 4", it returns following error:

Undefined symbols for architecture x86_64: ... ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

As I use GPU in tensorflow without any issues, I doubt that my CUDA setting has not done or something.

I searched similar issues here but I am the only person who's having this issue as it seems. There's no issue on compilation if I don't put cuda backend.

If I missed a significant step here or if anyone who's familiar with this error, please help. I wasted more than 6 hours because of this.

make.log.zip

It would be nice to have operations that allow you to do things like

• concat_batch: concatenate multiple expressions into a single batched expression
• pick_batch_elements: pick only a subset of the elements from a batched expression

Hello,

I'm trying to install dynet on my local machine and I keep getting an error while importing dynet in python.

import dynet as dy Traceback (most recent call last): File "", line 1, in File "dynet.py", line 17, in from _dynet import * ImportError: dlopen(./_dynet.so, 2): Library not loaded: @rpath/libdynet.dylib Referenced from: /dynet-base/dynet/build/python/_dynet.so Reason: image not found

I'm using:

• MBP w/ MacOS Sierra
• Eigen's default branch from bitbucket
• The latest dynet (w/ Today's commit that fixed TravisCI)
• boost 160
• python 2.7.10
• cmake 3.6.3
• make 3.81 (built for i386-apple-darwin11.3.0)

The make log also references that file c++ -bundle -undefined dynamic_lookup -arch i386 -arch x86_64 -Wl,-F. build/temp.macosx-10.12-intel-2.7/dynet.o -L. -L/dynet-base/dynet/build/dynet/ -L/dynet-base/dynet/build/dynet/ -ldynet -o /dynet-base/dynet/build/python/_dynet.so ld: warning: ignoring file /dynet-base/dynet/build/dynet//libdynet.dylib, file was built for x86_64 which is not the architecture being linked (i386): /dynet-base/dynet/build/dynet//libdynet.dylib

Could you advise?

Thanks, Florin.

Currently, the compiled Cython file, _dynet.so depends on libdynet. This has a couple of disadvantages such as:

• Installation can be clumsy (e.g., setting LD_LIBRARY_PATH in Linux, DYLD_LIBRARY_PATH in macOS to load libdynet)
• Not easy to deploy to servers.

This change eliminates the dependency by creating a static library of dynet, making the installation and deployment easier. The idea is to link the static library rather than the shared/dynamic library when generating _dynet.so.

The static and shared/dynamic libraries are generated from an object library (it's just a collection of object files) [1]. By creating an object library, we can avoid compiling object files for both libraries.

This change is 

We have created SWIG bindings so that we can use DyNet from Scala. They are pretty comprehensive, with lots of documentation and tests and examples, and we are actively using DyNet from Scala code.

Other than a few lines in the top level CMakeLists, all of our changes are under the new swig directory (and are hidden behind a flag which is OFF by default).

We wanted to contribute this back, as it seems like something that could be useful to a lot of people.

Incorporating this would require some sort of plan around keeping the bindings in sync with the root C++ code. Presumably that's already required for the Python bindings, so maybe it's not terribly hard.

Anyway, I know this isn't just a simple "LGTM" change, so let's discuss.

Trying to tag the repo and triggering a release is currently not working. Attached is a full-log (logs_buffer_detached.txt). Here are the interesting snippets.

So it seems that Error is thrown for each logging attempt. Later in the logs, the following issue occured which is probably more severe:
