Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

[rodolfowenceslau]

Hello!
I need help.
I created a virtual machine with Ubuntu (64-bit) and 6144 MB and 2 processors.
I installed Pycharm and followed the steps and example on the installation page (https://automl.github.io/auto-sklearn/master/installation.html#windows-osx-compatibility).
When executing the sample code the error occurs in the following excerpt "automl.fit (X_train, y_train)" the message is: Process finished with exit code 139 (interrupted by signal 11: SIGSEGV). Am I doing something wrong? Attached are some prints.

Hi, thanks for the report. Could you please upload the logfile written by Auto-sklearn. It is usually stored in a directory starting with autosklearn_tmp_ under /tmp.

I must admit that I'm a bit puzzled as Auto-sklearn does not even try a single configuration. Could you please check two things:

• which SWIG version is installed
• whether you can run one of the examples from the SMAC3 repository

SWIG Version 4.0.1
any example? I say because I'm new to python!

SWIG Version 4.0.1

Unfortunately, we don't support SWIG4. Is it possible that you install SWIG3? Just out of curiosity, what Linux and which version is this?

any example?

Yes, any example is fine. It's just about triggering the bug without Auto-sklearn. You could for example use https://github.com/automl/SMAC3/blob/master/examples/SMAC4HPO_rosenbrock.py

Same issue here.

I have uninstalled SWIG4 and install SWIG3 now.

The only example I could run without the message "Process finished with exit code 139 (interrupt by signal 11: SIGSEGV)" is "hyperband_mlp.py".

Any clue what is causing the issue?

Thanks.

[mfeurer]

Did you completely reinstall the pyrfr with pip install pyrfr --no-cache?

[JohnsonZhouUoa]

Hi,

Should it be like this?

Thanks.

[mfeurer]

Yes, almost. It does not re-install because the pyrfr is already installed. Could you please do

pip uninstall pyrfr
pip install pyrfr --no-cache

What would be a straightforward way to install swig3?

[mfeurer]

What would be a straightforward way to install swig3?

conda install swig=3 which gives:

The problem is that in a new ubuntu swig 4 gets installed and if you install swig 3 it has an incompatible name swig3.0. Maybe its possible to resolve this dependency somehow as I think a lot of people will have trouble with this dependency.

What worked for me:
sudo apt-get remove swig
sudo apt install swig3.0
ln -s /usr/bin/swig3.0 /usr/bin/swig
pip uninstall pyrfr
pip install pyrfr --no-cache

I came across the same issue and was suspecting this! Thank you! This should be added to the auto-sklaern docs until swig 4 is supported
