Python environment creation failed (time-series forecast)

Hi,

When I try to set up the time series forecast plugin I get the following error. I tried to re-create and update by rebuild env but still unsolved.

Thank you for all your help already.

Hi,

Welcome to the Dataiku Community.

Could please try to installing the following dependencies and try rebuilding the env again. 

For yum (CentOS, RHEL...):

sudo yum install python3-devel

For Ubuntu :

Hello, I also have trouble creating the environment, i've attached the error log. i've tried running 

sudo apt-get install python3-dev 

but it is already correctly installed. 

first error in the attached file is (see complete error log in attachment):

Hi Xavier, 

Looking at the error it seems like the gcc compiler is failing to install ujson.

It could be a bug in the kernel that looks similar to : 

https://bugs.launchpad.net/ubuntu/+source/python3.6/+bug/1768644

Suggests a workaround would be to run :

sudo apt-get install -y dpkg-dev

 

Let me know if that helps.

Hello @AlexT ,

thank you for your answer; it really looks like the issue you're mentioning and I tried your command. 

I still have the bug, which seems to be around the build of the wheel for ujson which is failing for some reason

 (i have attached the complete error log as attachment)

I tried your suggestion but it doesn't seem to work; any other suggestion? 

thank you, I really appreciate the help!

Hi,

The error "fatal error: Python.h: No such file or directory " suggests that python-devel is not installed.

Can you try re-running :

Ubuntu:

sudo apt-get install python-dev
sudo apt-get install python3-dev 

For yum (CentOS, RHEL...):

sudo yum install python-devel 
sudo yum install python3-devel

Hello @AlexT 

they are already installed: 

sudo apt-get install python-dev

python-dev-is-python2 is already the newest version (2.7.17-4).

Hi,

So the python3-dev version is 3.8. The logs show the code env is using Python 3.6. 

Can you try installing python3.6-dev :

sudo apt-get install -y python3.6-dev

If that does not work you will need to add the following repository :

sudo add-apt-repository -y ppa:deadsnakes/ppa

If that does not resolve the issue can you please confirm :

1) exact OS version

2) How python 3.6 was installed

Hello @AlexT 

actually even if sudo apt-get install python3-dev was already installed,  i looked on the internet for answers regarding your specific comment, and i found a solution:

"sudo apt-get install python3.6-dev" did it!

i'm not sure why the "sudo apt-get install python3-dev" wasn't sufficient, but I was able to build the environment successfully

thanks a lot for helping!

Most of the time these are dependency-issues. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications. When encountering this error please note before the error it may say you are missing a package or header file — you should find those and install them and verify if it works

For Python 2.x use:

$ sudo apt-get install python-dev

If you using python3, try to replace python-dev with python3-dev

For a specific version of Python 3, replace x with the minor version in

$ sudo apt-get install python3.x-dev
