[MXNET-651] MXNet Model Backwards Compatibility Checker (#11626)
* Added MNIST-MLP-Module-API models to check model save and load_checkpoint methods * Added LENET with Conv2D operator training file * Added LENET with Conv2d operator inference file * Added LanguageModelling with RNN training file * Added LamguageModelling with RNN inference file * Added hybridized LENET Gluon Model training file * Added hybridized LENET gluon model inference file * Added license headers * Refactored the model and inference files and extracted out duplicate code in a common file * Added runtime function for executing the MBCC files * Added JenkinsFile for MBCC to be run as a nightly job * Added boto3 install for s3 uploads * Added README for MBCC * Added license header * Added more common functions from lm_rnn_gluon_train and inference files into common.py to clean up code * Added scripts for training models on older versions of MXNet * Added check for preventing inference script from crashing in case no trained models are found * Fixed indentation issue * Replaced Penn Tree Bank Dataset with Sherlock Holmes Dataset * Fixed indentation issue * Removed training in models and added smaller models. Now we are simply checking a forward pass in the model with dummy data. * Updated README * Fixed indentation error * Fixed indentation error * Removed code duplication in the training file * Added comments for runtime_functions script for training files * Merged S3 Buckets for storing data and models into one * Automated the process to fetch MXNet versions from git tags * Added defensive checks for the case where the data might not be found * Fixed issue where we were performing inference on state model files * Replaced print statements with logging ones * Removed boto install statements and move them into ubuntu_python docker * Separated training and uploading of models into separate files so that training runs in Docker and upload runs outside Docker * Fixed pylint warnings * Updated comments and README * Removed the venv for training process * Fixed indentation in the MBCC Jenkins file and also separated out training and inference into two separate stages * Fixed indendation * Fixed erroneous single quote * Added --user flag to check for Jenkins error * Removed unused methods * Added force flag in the pip command to install mxnet * Removed the force-re-install flag * Changed exit 1 to exit 0 * Added quotes around the shell command * added packlibs and unpack libs for MXNet builds * Changed PythonPath from relative to absolute * Created dedicated bucket with correct permission * Fix for python path in training * Changed bucket name to CI bucket * Added set -ex to the upload shell script * Now raising an exception if no models are found in the S3 bucket * Added regex to train models script * Added check for performing inference only on models trained on same major versions * Added set -ex flags to shell scripts * Added multi-version regex checks in training * Fixed typo in regex * Now we will train models for all the minor versions for a given major version by traversing the tags * Added check for validating current_version

# Model Backwards Compatibility Tests | ||
|
||
This folder contains the scripts that are required to run the nightly job of verifying the compatibility and inference results of models (trained on earlier versions of MXNet) when loaded on the latest release candidate. The tests flag if: | ||
- The models fail to load on the latest version of MXNet. | ||
- The inference results are different. | ||
|
||
|
||
## JenkinsfileForMBCC | ||
This is configuration file for jenkins job. | ||
|
||
## Details | ||
- Currently the APIs that covered for model saving/loading are : do_checkpoint/load_checkpoint, save_params/load_params, save_parameters/load_parameters(added v1.2.1 onwards), export/gluon.SymbolBlock.imports. | ||
- These APIs are covered over models with architectures such as : MLP, RNNs, LeNet, LSTMs covering the four scenarios described above. | ||
- More operators/models will be added in the future to extend the operator coverage. | ||
- The model train file is suffixed by `_train.py` and the trained models are hosted in AWS S3. | ||
- The trained models for now are backfilled into S3 starting from every MXNet release version v1.1.0 via the `train_mxnet_legacy_models.sh`. | ||
- `train_mxnet_legacy_models.sh` script checks out the previous two releases using git tag command and trains and uploads models to S3 on those MXNet versions. | ||
- The S3 bucket's folder structure looks like this : | ||
* 1.1.0/<model-1-files> 1.1.0/<model-2-files> | ||
* 1.2.0/<model-1-files> 1.2.0/<model-2-files> | ||
- The <model-1-files> is also a folder which contains the trained model symbol definitions, toy datasets it was trained on, weights and parameters of the model and other relevant files required to reload the model. | ||
- Over a period of time, the training script would have accumulated a repository of models trained over several versions of MXNet (both major and minor releases). | ||
- The inference part is checked via the script `model_backwards_compat_inference.sh`. | ||
- The inference script scans the S3 bucket for MXNet version folders as described above and runs the inference code for each model folder found. | ||
