Rasa without a GPU

Getting Started with Rasa
1

Hello,

I am trying to make Rasa work with a 2.1 capacty GPU (outside of the tensorflow_gpu minimum requierment.) Is it possible to use Rasa only with tensorflow CPU?

The error log that blocked me all day is the following :

$ rasa init

We are training our models on GPUs from time to time without any problems. What Rasa version are you using?

I’m using the most recent version, the error occured just after my rasa download with the $rasa init. :slight_smile:

My question is : is it possible to use rasa without a GPU in your machine? Or in this case a GPU that doesnt support Tensorflow?

The error message i got :

“no supported devices found for platform CUDA Abandon (core dumped)”

Tells me it can’t and i tried using manual instalation and other guide accessible on your documentation. Is there a way to use RASA using only tensorflow-CPU?

@Val Have you installed tensorflow-gpu on your machine? If you wish to use CPU only, just install tensorflow==1.15.0, that should work. In case you have both tensorflow and tensorflow-gpu installed and you know that your GPU is incompatible with tensorflow-gpu please uninstall tensorflow-gpu. Let us know if you face any further problem.

Problem solved! thanks a lot :slight_smile:

It’s another way to solve it. Need to remove tensorflow and install tensorflow-cpu.

pip uninstall tensorflow
pip install tensorflow-cpu
