Loading a process from myExperiment

colo

Hi,

I tried to open a project from myExperiment using the Community Extension.

The process doesn't open and the following exception is thrown:

Sep 13, 2011 10:07:07 AM com.rapidminer.io.community.MyExperimentConnection open
INFO: Downloading workflow from http://www.myexperiment.org/workflows/1724/download/loop_repository__amp__append_data_79565.
Exception in thread "ProgressThread" java.lang.NoSuchMethodError: com.rapid_i.deployment.update.client.ProgressReportingInputStream.<init>(Ljava/io/InputStream;Lcom/rapidminer/tools/ProgressListener;III)V

	at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source)
	at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
	at java.lang.Thread.run(Unknown Source)

Might there be something wrong on my side? I didn't use this extension for a long time, but it was working for me earlier.

I'm having a similar problem. In addition, I cannot upload processes anymore from the Community Extension. What is worse, I cannot export the process from RM in such a way that it could be uploaded manually to myExperiment. Could it be that the compatibility between RM and myExperiment is broken in 5.3?

My current setup:

RapidMiner 5.3.005
Community Extension 5.1.000

I've tried both under Ubuntu 12.10 and Win7, the same result. I've also tried running versions 5.2 and 5.3 with Java 6 and Java 7, none of these combinations seems to work. The Java error stack is the following:

Hi,

thanks for reporting. In fact there seems to be a compatibility problem.
We will investigate the issue and release a new version soon.

Best,

I have the same problem. Tried various older versions (5.0, 5.1 and 5.2) of RM without sucess. When would you expect a new version which would work with the community extension?

Many thanks,


Radek

Hi,

the new version of the Community Extension is already ready. But there is a bug in the API of MyExperiment.. Thus we will wait with the release of the new version until this bug is fixed.

Best,
Nils
