kedarbellare opened a new pull request #13769:  Clojure example for fixed label-width captcha recognition 
URL: https://github.com/apache/incubator-mxnet/pull/13769
 
 
   ## Description ##
   
   Adds an example for training a captcha OCR model and using the learned model for performing inference.
   
   ## Checklist ##
   ### Essentials ###
   Please feel free to remove inapplicable items for your PR.
   - [X] Changes are complete (i.e. I finished coding on this PR)
   - [X] All changes have test coverage:
   - Unit tests are added for small changes to verify correctness (e.g. adding a new operator)
   - Nightly tests are added for complicated/long-running ones (e.g. changing distributed kvstore)
   - Build tests will be added for build configuration changes (e.g. adding a new build option with NCCL)
   - [X] Code is well-documented: 
   - For new examples, README.md is added to explain the what the example does, the source of the dataset, expected performance on test set and reference to the original paper if applicable
   - [X] To the my best knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change
   
   ### Changes ###
   - [X] Captcha OCR training and inference with unit tests for training
   
   ## Comments ##
   I ran this on both osx and ubuntu linux but only with `:cpu`. However, I encountered memory issues while trying to train on a `:gpu`:
   ```
   Exception in thread "main" org.apache.mxnet.MXNetError: [19:18:33] src/storage/./pooled_storage_manager.h:143: cudaMalloc failed: out of memory
   ```
