ISSUE: Unable to connect to StanfordCoreNLPServer on Google Colab

Location

https://github.com/practical-nlp/practical-nlp/blob/master/Ch9/01_Aspect_Based_Sentiment_analysis.ipynb

Current Behavior

unable to connect to StanfordCoreNLPServer

Expected Behavior

connected to StanfordCoreNLPServer

Possible Solution

can use Stanza, but give slightly different result (sentiment analysis on words, instead of sentence)

Steps to Reproduce

  1. download and install java:
    import os
    !apt-get install openjdk-8-jdk-headless -qq > /dev/null
    os.environ["JAVA_HOME"] = "/usr/lib/jvm/java-8-openjdk-amd64"
  2. download stanford-corenlp:
    !wget "https://nlp.stanford.edu/software/stanford-corenlp-latest.zip"
    !unzip "stanford-corenlp-latest.zip"
  3. change directory:
    cd stanford-corenlp-4.2.0/
  4. connect to server:
    !java -mx5g -cp "./*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -timeout 10000
    if using port 9000 (even though nothing else is using this port):
    [main] INFO CoreNLP - --- StanfordCoreNLPServer#main() called ---
    [main] INFO CoreNLP - Server default properties:
    (Note: unspecified annotator properties are English defaults)

if using port 9001 (freeze at this point):
[main] INFO CoreNLP - --- StanfordCoreNLPServer#main() called ---
[main] INFO CoreNLP - Server default properties:

Context (Environment)

running the notebook on colab (on Windows 10)
python 3.6.9
pycorenlp-0.3.0
Please provide any more details you feel necessary

Possible Implementation

this is an option: https://colab.research.google.com/github/stanfordnlp/stanza/blob/master/demo/Stanza_CoreNLP_Interface.ipynb
