Python test failed

[jasonppy]

Hi,

Since I couldn't get gtn to compile with cuda (see our conversation in this issue), I turned off all CUDA related options. Specifically, I changed https://github.com/gtn-org/gtn/blob/master/CMakeLists.txt#L17 to OFF, and deleted https://github.com/gtn-org/gtn/blob/master/bindings/python/CMakeLists.txt#L28.

With the above changes, running

mkdir -p build && cd build
cmake ..
make -j $(nproc)

were successful

and running

cd bindings/python
conda install setuptools
python setup.py develop

were also successful,

However, when running

python -m unittest discover bindings/python/test

I also commented https://github.com/gtn-org/gtn/blob/master/bindings/python/gtn/init.py#L21, and delete ./bindings/python/test/test_cuda.py

I got output:

...F................................F...........

Thanks for your time!

I'm seeing this as well. Just got the same error after building successfully with CUDA bindings:

@jasonppy Are you seeing any errors coming up as a result of these failing tests when using the library?

I just checked and the "simple example graph" example works as intended:

python bindings/python/examples/simple_graph.py
