While we always try to test each release as much as we can, inevitably some bugs will always slip through unnoticed. This page only shows the most important bugs that have surfaced after the release was made.
Remember to also check the bugs on the project website. To stay up to date with the latest news and releases, we also recommend subscribing to our newsletter here. Traffic will be kept to a minimum and you can unsubscribe at any time.
If you happen to encounter something not listed here, please report it.
Version 5.0
| Bug | Duplicate samples and samples with NaN/Inf values are not filtered properly. |
|---|---|
| Status | Fixed in SVN. |
| Workaround | Wait for next release. Simulators that may return invalid values or duplicate samples should be avoided until then. |
| Bug | You get the following error: "Failed to create object of type ANNGeneticInterface, error is "Undefined variable "logger" or class "logger.severe" |
|---|---|
| Status | Fixed in SVN. |
| Workaround | Simply remove the offending line or set complex handling to split or modulus (you are trying to model complex data with ANNs). |
Version 4.2
| Bug | Loading the random state from file gives a directory does not exist error. |
|---|---|
| Status | Fixed in SVN. |
| Workaround | Upgrade to the next version. |
| Bug | When starting the toolbox for the first time you get an error like "The class ContextConfig cannot be found, make sure java is running" |
|---|---|
| Status | Fixed in SVN. |
| Workaround | This is a bug in Matlab itself. Please contact us for instructions on how to fix this. |
| Bug | When starting the toolbox for the first time you get an error like "The class be.ac.ua.coms.m3.config.Util has no field or method named genHash" |
|---|---|
| Status | Fixed in SVN. |
| Workaround | This is a bug in Matlab itself. Please contact us for instructions on how to fix this. |
| Bug | When the TestSamples measure is used without a dataset the testset is not calculated correctly!! |
|---|---|
| Status | Fixed in SVN. |
| Workaround | Replace the line 'tmp(testSet,:) = [];' by 'tmp(testSet,:) = NaN;' |
| Bug | The optimization framework may fail in specific circumstances |
|---|---|
| Status | The framework is currently under redesign and a much improved, more robust, version will be released with 5.0 |
| Workaround | Upgrade to 5.0 when it becomes available. |
| Bug | The BatchModelBuilder fails with an error |
|---|---|
| Status | Fixed in SVN |
| Workaround | Simply remove the offending line |
Version 4.1
| Bug | The maximum number of samples is not respected in a correct way |
|---|---|
| Status | Fixed in SVN. |
| Workaround | Upgrade to 4.2 when it becomes available. |
| Bug | The toolbox crashes when you pass samples on the command line |
|---|---|
| Status | Fixed in SVN. |
| Workaround | On the offending line replace "scale(..)" by "scaleColumns(...)". |
Version 4.0
| Bug | The toolbox goes into a seemingly infinite loop if u are using the Matlab sample evaluator and there is an error in your matlab function. |
|---|---|
| Status | Wont fix |
| Workaround | This is due to the poor Java -> Matlab interface and thus there is little we can do about it. It is best to make sure your function runs without error by running it manually. |
| Bug | In some rare cases the toolbox goes into an infinite loop when using the grid sample selector. |
|---|---|
| Status | Fixed in SVN. |
| Workaround | This happens in some rare cases, and is due to the way the grid SE works. This will be fixed in the next release. In the meantime, if you run into the problem use a different sample selector or combine the grid SE with a different SE (e.g., the random SE) using the CombinedSampleSelector. |
| Bug | If the first component inside the <Plan> tag is a component that is overridden in the <Run> tag, a NullPointerException occurs |
|---|---|
| Status | Fixed in SVN. |
| Workaround | This is a very obscure bug, simply make sure that the first component in your <Plan> tag is one that is NOT overridden in a <Run> tag. Use for example <ContextConfig>. |
| Bug | When modeling the same output multiple times in parallel, some profilers may interfere with each other |
|---|---|
| Status | Fixed in SVN. |
| Workaround | Avoid modeling the same output multiple times in the same run. Try using different runs or turning off the profilers that give problems. |
Version 3.3
| Bug | Loading a saved model file from disk gives warnings and in some cases even errors (see the FAQ) |
|---|---|
| Status | fixed in the latest snapshots |
| Workaround | if you are lucky you can just ignore the warnings and it should work, in some cases it wont and you will need to upgrade |
| Bug | Movie generation gives problems on windows |
|---|---|
| Status | Fixed |
| Workaround | Use a different operating system (Linux, OSX, ...) or upgrade and edit src/matlab/modelbuilders/@AdaptiveModelBuilder/createMovie.m file so it creates an avi instead of a mov file (Warning: the avi file is not compressed and may be very big!) |
