Machine Learning Toolkit: Why am I constantly getting python error "Operation not permitted" when trying to execute 'fit' command?

[fkurbatov]

Every time I try to run a linear prediction sample (for example "Predict VPN Usage") I get the following error:

Error in 'fit' command: [Errno 1] Operation not permitted: '/opt/splunk/etc/apps/Splunk_SA_Scientific_Python_linux_x86_64/bin/linux_x86_64/bin/python'

Detection of numeric outliners (which obviously doesn't need 'fit') works fine.

Here is what I get in mlspl.log:

1491518277.011762 2017-04-07 01:37:57,011 ERROR [mlspl] [die] [Errno 1] Operation not permitted: '/opt/splunk/etc/apps/Splunk_SA_Scientific_Python_linux_x86_64/bin/linux_x86_64/bin/python'

Please advice.

Thanks,

Hi ,

Can you please check if your app was installed by same user as splunk? Depending on how the app was installed, it can be messed up (e.g. it was installed by root but splunk runs as a separate user)

Thanks

That was exactly my case.

Thank you very much!
