Error: Illegal instruction when run rasa

Please help me. I have installed rasa-x by follow pip install rasa-x --extra-index-url (python 3.7), and completed, no error. But when i run: rasa init --no-prompt , the error: Illegal instruction Please help me Capture


Hi there,

This may be unrelated, but this is a known issue with recent tensorflow versions on certain cpus, especially older models ( see python - Illegal instruction (core dumped) after running import tensorflow - Stack Overflow ). Possible solutions for that specific issue include building tensorflow from source on your machine.

An alternative approach is to use an anaconda environment and use conda to install tensorflow before installing rasa with pip. Conda is significantly better at dealing with dependencies than pip, because it also handles binary dependencies.

However, maybe this error is already known to the rasa team, or has a different reason in this context, so keep this in mind as a last resort solution, I am sure someone can come up with better options!

Best, Tao

Hey @1412392, did you end up being able to use rasa init successfully?

I’m having the same issue. I’ve created a python3.7 env in miniconda and install rasa-x inside it. In case it is a CPU compatability issue, I’m running Intel® Xeon® CPU E5-2620 v4. Will try to build TF from source and return with an update…

update I compiled tensorflow and now I can call rasa. Using these instructions, and build target 1.13.2.

Hi @Krogsager @erohmensing and @taotsetung,

Can you please help me.

My env is linux server. when i have the below env Python 3.6 rasa-x = 0.20.0 rasa=1.2.0 tensorflow = 1.13.0 then i faced this issue: “2020-02-25 00:30:47.132923: F tensorflow/core/platform/] The TensorFlow library was compiled to use AVX instructions, but these aren’t available on your machine. Aborted (core dumped)”

Then i updated tensorflow to 1.15.0 then i was forced to update all other dependencies like rasa-x = 0.25.0 rasa = 1.7.2 Now am facing the below issue while typing rasa init command: “Illegal instruction (core dumped)”

Need help in resolving this issue.

“Illegal instruction (core dumped)” indicates that some C code crashed. You could try do debug that using PDB, but in my experience you are heading a long road that might lead to nowhere.

TensorFlow library was compiled to use AVX instructions, but these aren’t available on your machine.

Ensure that your CPU supports AVX instructions, otherwise get a different machine. Sorry.

Hi @Krogsager,

Can you please let me know what is the suitable hardware configuration for successful installation of RASA in LINUX SERVER. Facing number of issues, and i don’t see a straight forward resolution to the issues that am facing in linux server. Please help…

If you use conda evnironment, you uninstall the tensorflow you are using, and install using conda install tensorflow-mkl

This will take care of no gpu and having no avx to get you running.

Those packages for tensorflow can be found using… conda search tensorflow

What is the solution for this?

My machine does not support AVX… What is the workaround?

I tried installing tensor flow through conda and then pip install rasa, facing the same ‘illegal instructions’ error.

Kindly help!

Anyone here???

I’m having the same issue when i run “rasa init” although i install rasa by “pip install rasa” successfully!I run on Ubuntu 18.04 server @erohmensing
