fold not loading after installation

[madian9]

I installed fold using pip as recommended by the instructions, however when I try to import it I get an error. Any suggestions on how to fix this issue:

tensorflow-gpu works well, version is 1.1.0 python 2.7 on ubuntu 16.04 also found this error:

tensorflow.python.framework.errors_impl.NotFoundError: /usr/local/lib/python2.7/dist-packages/tensorflow_fold/loom/_deserializing_weaver_op.so: undefined symbol: _ZN10tensorflow6tensor5SplitERKNS_6TensorERKNS_3gtl10ArraySliceIxEE

please give some advice

It looks like your tensorflow version is newer than the tensorflow_fold binary. You can try compiling from source, or you can wait until I have a chance to push a new binary. Sorry about the frustration...

Ran into the same problem... Also, compiling and installing tensorflow a23f5d7f7757623a4ea8c6e1d743d178a0c561c5 did not help. The only effect was that the undefined symbol changed to _ZN10tensorflow7strings8internal9CatPiecesESt16initializer_listINS_11StringPieceEE

Which versions would we need to get it working?

[tadpole]

I got the same error with tensorflow 1.1.0, but I fixed it with tensorflow 1.0.0.

[NonvolatileMemory]

got the same error...

[pachiras]

Same here.

[louner]

me too, only TF1.0.0 works

[evelkey]

Newest version (with tf1.4) has the following error:

tensorflow.python.framework.errors_impl.NotFoundError: ***/python3env/lib/python3.5/site-packages/tensorflow_fold/loom/_deserializing_weaver_op.so: undefined symbol: _ZN10tensorflow10DEVICE_CPUE

Built from sources with bazel 6.1 with fully recursive cloning (tried bazel 5.4 too).

[idavydov]

I have the same problem as @evelkey has.

I followed sources.md. Essentially git pull, ./configure, basel build fold and tensorflow, and them installed wheels in a clean virtualenv. Everything compiled from source.

Getting the same error:

tensorflow.python.framework.errors_impl.NotFoundError: /home/idavydov/ml/build/env/lib/python3.4/site-packages/tensorflow_fold/loom/_deserializing_weaver_op.so: undefined symbol: _ZN10tensorflow10DEVICE_CPUE

There are a couple of warnings, when building; it seems that bazel does not see options from tensorflow:

Has anyone gotten this fixed? I'm getting an undefined symbol: _ZTIN10tensorflow8OpKernelE error as well.

Today is my first time using Tensorflow/fold and I installed using the latest whl, and its not working for me using Ubuntu 16.04, tensorflow-gpu (installed using lambda stack), CUDA Version: 10.0, and NVIDIA-SMI 410.78.
