Local Pipeline not working (Fail to load models)

[flackbash]

Hello,

when using the local pipeline because the remote pipeline does not seem to be available anymore (see #129), I get the following message

INFO:ccg_nlpy.pipeline_config:Using local pipeline
ERROR:ccg_nlpy.local_pipeline:Fail to load models, please check if your Java version is up to date.
ERROR:ccg_nlpy.local_pipeline:JVM exception occurred: edu/illinois/cs/cogcomp/pipeline/main/PipelineFactory java.lang.NoClassDefFoundError

Here is some information about my Java installation

# echo $JAVA_HOME
/usr/lib/jvm/java-8-openjdk-amd64/
# java -version
openjdk version "1.8.0_362"
OpenJDK Runtime Environment (build 1.8.0_362-8u372-ga~us1-0ubuntu1~18.04-b09)
OpenJDK 64-Bit Server VM (build 25.362-b09, mixed mode)

I removed old models and downloaded them again as suggested in #122 but the error persists.

Any help is appreciated.

The problem is that the models cannot be downloaded, even though the download command ended with Model download successful.

So the problem seems to be that the server hosting the models is down, just like the server hosting the remote pipeline, rendering ccg_nlpy unusable.

This library is somewhat outdated now (not much activity in the recent few years).
I suggest you try other libraries (e.g., Huggingface model hub) for better models.
