Cannot save ALS model #12

Closed jwang727 closed 7 years ago

jwang727 commented 7 years ago

When I try to save a trained ALS model like follows:

model = ALS.train(all_ratings_train, rank, numIterations, Lambda) import os path = os.getcwd() model.save(sc, path)

I get the following error:

Py4JJavaError Traceback (most recent call last) /home/ubuntu/spark/spark-2.1.0-bin-hadoop2.7/python/pyspark/sql/utils.py in deco(*a, *kw) 62 try: ---> 63 return f(a, **kw) 64 except py4j.protocol.Py4JJavaError as e:

During handling of the above exception, another exception occurred:

I'm getting the same issue, would have to assume this is the important bit:

/home/ubuntu/spark/spark-2.1.0-bin-hadoop2.7/python/pyspark/mllib/util.py in save(self, sc, path) 404 if not isinstance(path, basestring): 405 raise TypeError("path should be a basestring, got type %s" % type(path)) --> 406 self._java_model.save(sc._jsc.sc(), path)

It appears to be expecting a basestring, which no longer exists in Python 3. Not the end of the world, just have to generate the model each time which is time consuming :(

We looked into this error and you are both trying to save the model correctly, as described in docs. The MatrixFactorizationModel implements Serializable and Saveable interfaces, however saving the model gives us the above error and serialization using JSON or Pickle modules fails too. This seems to be affecting only Python implementations.

How to proceed with the coursework: If you are in the phase of exploring the datasets and building your first model you could use a subset of the ratings file as described in FAQ, point 3. Once you are confident with your work, you could rerun your spark job (Task 1-6) with the full dataset, and while it is running focus on other parts of the coursework (e.g. designing the Neo4j queries).

If we (or one of the students) find any solution to this, we will point you to it.

Yeah in the end I just used the smaller dataset, thanks.

I am also getting the same issue. How to resolve this issue? Has anyone any Idea?
