Analytics model import error
I try to import an Analytics model exported from Moodle 3.9.1 into another Moodle 3.9.1 installation, but I get error:
analytics/errorimportmodelresult Error code: errorimportmodelresult line 588 of /lib/mlbackend/python/classes/processor.php: moodle_exception thrown line 438 of /lib/mlbackend/python/classes/processor.php: call to mlbackend_python\processor->exec_command() line 131 of /analytics/classes/model_config.php: call to mlbackend_python\processor->import() line 1613 of /analytics/classes/model.php: call to core_analytics\model_config->import() line 58 of /admin/tool/analytics/importmodel.php: call to core_analytics\model::import_model() I also get the following PHP Notice in webserver log:
PHP Notice: The indicator 'indicator:RESOURCE_2' should include a 'indicator:RESOURCE_2_help' string to describe its purpose Any idea why the model import fails?
I use the moodlemlbackend v2.6.5 with Moodle 3.9.1.
I found interesting note in the following release note which relates to model import problems and moodlemlbackend v2.6.5: 2.6.5: Merge pull request #51 from catalyst/catalyst-fix-tests
Fixing import/export models.
Might be the error related to this fix in any way?
Is the model you exported from a previous moodlemlbackend version? - eg something you've stored previously rather than one generated with the v2.6.5 mlbackend? If so, you'll need to re-train - pretty sure you can't take a model that you generated on an old version and then use that same model on the new mlbackend version.
Also - you really need to update that moodle site... 3.9.1 almost 2 years old and is missing a lot of bug and security fixes.
