Azure: importing not already existing packages in 'src'

Question

I have an experiment in which a module R script uses functions defined in a zip source (Data Exploration). Here it's described how to do about the packages not already existing in the Azure environment.

The DataExploration module has been imported from a file Azure.zip containing all the packages and functions I need (as shown in the next picture).

When I run the experiment nothing goes wrong. At the contrary, watching the log it seems clear that Azure is able to manage the source.

The problem is that, when I deploy the web service (classic), if I run the experiment I get the following error:

FailedToEvaluateRScript: The following error occurred during evaluation of R script: R_tryEval: return error: Error in .zip.unpack(pkg, tmpDir) : zip file 'src/scales_0.4.0.zip' not found , Error code: LibraryExecutionError, Http status code: 400, Timestamp: Thu, 21 Jul 2016 09:05:25 GMT

It's like he cannot see the scales_0.4.0.zip into the 'src' folder.

The strange fact is that all used to work until some days ago. Then I have copied the experiment on a second workspace and it gives me the above error.

I have also tried to upload again the DataExploration module on the new workspace, but it's the same.

Answer 1

I have "solved" thanks to the help of the AzureML support: it is a bug they are trying to solve right now.

The bug shows up when you have more R script modules, and the first has no a zip input module while the following have.

Workaround: connect the zip input module to the first R script module too.
