Celery raised unexpected LookUp Error

I am using celery for my django project. 

java_path = "/your/Java/jdk/home/java.exe
os.environ['JAVAHOME'] = java_path

st = POSTagger('/your/postagger/models/path/english-bidirectional-distsim.tagger','/your/postagger/jar/file/path/stanford-postagger.jar')

tag = st.tag([key])

here the key is a list of feature words.

I got following errors, when using celery to execute:

raised unexpected: 
           LookupError('\n\n===========================================================================\nNLTK 
        `was unable to find the java file!\nUse software specific configuration paramaters or set the JAVAHOME environment`

I have set java_path and javahome and I would like to know why still thess errors occur?

Solution

  • my environment is MAC.

    The problem is the java_path, should be:

    java_path = "/your/Java/jdk/home
