Could not identify NUMA node of platform GPU

I try to get Tensorflow to start on my machine, but I always get stuck with a "Could not identify NUMA node" error message.

I use a Conda environment:

Here is the error code:

>>> import tensorflow as tf
>>> tf.Session()

  what():  std::bad_alloc

Unfortunately, I have no idea what to do with the error code.

If you are getting this error on mac machine and error message includes this line Metal device set to: Apple M1 or any other chip than uninstall tensorflow-metal will resolve error.

pip uninstall tensorflow-metal

I had the same issue and I finally found out that it is because you used Adam to optimize the model. Once you use another optimizer it should work.

I could fix it with a new conda enviroment:

conda create --name tf python=3
conda activate tf
conda install cudatoolkit=9.0 tensorflow-gpu=1.11.0

A table of compatible CUDA/TF combinations is available here. In my case, the combination of cudatoolkit=9.0 and tensorflow-gpu=1.12, inexplicably led to an std::bad_alloc error. However, cudatoolkit=9.0 and tensorflow-gpu=1.11.0 works fine.
