My Moodle site required I upgrade its database from MySQL 5.7.3 to MariaDB 10.2. I upgraded it to 10.3 through the MySQL/MariaDB Upgrade package on WHM, but after the upgrade, it gave this error:
"The MySQL/MariaDB server is not currently running. If this is not intentional, you may experience problems with your upgrade."
Due to this, my PhpMyAdmin has not been working with an error:

I dig into code and find this two references:

But Iam not a programmer so any idea is greatly appreciated.
I tried to uninstall sympy-1.6 and install sympy-1.5 but that doesn't work.
Thanks for your time.
Daniel
I have managed to found the answer.
The problem is on sympy version 1.6 so I downgraded it to version 1.5.1 with pip3.
I had a similar issue, the problem seems to be that you have to install sympy for python2 not for python3. Install it with pip and then try typing in octave
sympref diagnose
And it will tell you that the current interpreter is python3, you got to change this.
setenv PYTHON python2
sympref reset
Because apparently the symbolic package was developed for python2.
I hope I could help you.
I have installed (on Windows machine (Win7 64bit)):
python 3.5.0 and sympy 0.7.6.1
octave 4.0.0.0 and symbolic 2.2.2
This is what I get when I try to do anything with more than one operator:
>> pkg load symbolic

I have just got the release pipeline working with Google's push to deploy on App Engine.

I logged into the VM and noticed that the files are located at for instance:

How do I se the path universally in the VM ?
