Errors when using opencog/docker for GHOST

[joejnke]

I am using docker for practicing on this GHOST tutorial and i get these two errors :

1. misc-error (#f ~A ~S (no code for module (opencog)) #f)

2. unbound-variable

The first one can be avoided by adding (add-to-load-path "/usr/local/share/opencog/scm") and (add-to-load-path ".") before loading the opencog modules. But, this still solve it after running this cell 6 times. Till the sixth run, it gives misc-error and then after running the rest of the cells except the one with (set-relex-server-host) gives the unbound-variable error.
How can these be solved, specially the unbound-variable ?
