Fixing the error when running main.py

[azinoma]

Hi,

Simon and Bora figured out how to solve the error which appeared for most of us when running main.py.

A good way of solving it is:

1. when you are logged onto the cluster, go to your home directory using cd (normally you should be there already, but a cd doesn't hurt).
2. type vim .bashrc so that you are able to edit the bashrc file
3. press i so that you are in insert mode.
4. paste
   module load python
export LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH
export IPOPT_DIR="/home/rccguest1410/OSE2019/day1/SparseGridCode/pyipopt_midway/Ipopt-3.12.5/build"
export LD_LIBRARY_PATH=$IPOPT_DIR/lib:$LD_LIBRARY_PATH

(you need to use ctrl + shift + v for pasting) and replace the four digits in rccguest1410 by the last four digits of your yubikey.
5. press escape to exit the insert mode
6. type :wq to save the changes and exit vim.

Exit the terminal and log on again.
Now it should work.
Keep us posted if not.

Hi,

I am very sorry, but it seems this is not a permanent solution.
So far we didn't find a better way than doing the following every time you log on to the cluster:

1. module load python
2. cd OSE2019/day1/SparseGridCode/pyipopt_midway/
3. source setup_env.sh

It's a bit annoying but this seems to work for everybody.
Let me know if not.
