Kats installation throws gcc error

[psxpa3]

Hello,

I am trying to install Kats on Linux server, and while installing KATS getting error w.r.t fbprophet. The dependency tree that I could understood is KATs-> fbprophet -> Pystan -> gcc.

The default versions of that is being installed by KATS is 2.19.0.1 which is the reason that fbprophet is not being installed, and erroring out with this trace

However, when I manually installed Pystan with this version 2.18.0.0, and then fbprophet 0.6 version could be installed manually. However, I do not know how while installing just kats other dependency specific versions can be specified. Could you please help me with the same. I have been trying it a lot, but have not gotten any progress.

Thank you very much for your help.

I am not sure about my fix, but : it seems like you are using python 3.6. Try using conda to create a virtual environment with python 3.7/3.8/3.9 and install kats in this environment. It worked for me with python 3.9 virtual env.

One thing I realised installation of kats in Windows is not possible. Therefore u need to create a virtual environment to resolve this thing. If u are installing kats with 'pip install kats', it was giving me error despite of successful installation. So I uninstalled it and later re-installed it directly from the source using the following command

'pip install kats -i https://mirrors.aliyun.com/pypi/simple/' .

May be this helps!
