modernmt: Cannot load my engine - failed to start node

Hello MMT,

Not sure what I am having some issues with MMT, especially after porting my old engine.

Here is what I see in the terminal after running ./mmt start

Starting MMT engine ‘default’… OK Loading models… FAIL ERROR Unexpected exception: Exception(‘failed to start node, check log file for more details: /home/mlearner/ModernMT/runtime/default/logs/node.log’,)

and here is the node.log output.

By the way, I have done clean build already using these commands:

`git checkout – . git clean -fd .

rm -rf build/* git pull origin master

cd vendor ./compile cd …/src mvn clean install`

I also noticed something else:

According to this issue , the command was:

extras/porting/convert_from_v2.0.2_to_v2.0.3 --engine-path engines/default

But now I see a different script convert_from_v2.0.2_to_v2.1in ‘ModernMT/extras/porting’

Any idea?

I hope there is a quick fix.

Thanks, Mohamed
