* add subgraph instead of constant with fixed shape to allow model have undefined batch * updated transformation (not checked yet) * changed ReverseV2ToReverseSequence to support dynamic shapes/reshape; added transformation to reverse_tensor_iterator to support new subgraph got from ReverseV2ToReverseSequence * remove changes that should not be on this branch * added tests; fixed old transformation * added delete of reversesequences to avoid run of transformation twice * fixed pattern check for case with dynamic value for input of reversesequence * Revert "fixed pattern check for case with dynamic value for input of reversesequence" This reverts commit0c04164e* Revert "added delete of reversesequences to avoid run of transformation twice" This reverts commitfcb7de9c* reversed changes in reverse_tensorr_iterator for Squeeze case; update reverse_tensor_iterator with shapeof subgraph added permutations for attributes to pass layer test * minor fix for dynamic shape * updated test; fixed backward compatibility in reverse_tensor_iterator transformation * revew comments fixed: added comments; refactoring done; fixed framework name saving for rank = 1 * minor review fixes * small fix
Prerequisites
Model Optimizer requires:
-
Python 3 or newer
-
[Optional] Please read about use cases that require Caffe* to be available on the machine in the documentation.
Installation instructions
- Go to the Model Optimizer folder:
cd PATH_TO_INSTALL_DIR/tools/model_optimizer
-
Create virtual environment and activate it. This option is strongly recommended as it creates a Python sandbox and dependencies for the Model Optimizer do not influence global Python configuration, installed libraries etc. At the same time, special flag ensures that system-wide Python libraries are also available in this sandbox. Skip this step only if you do want to install all Model Optimizer dependencies globally:
- Create environment:
virtualenv -p /usr/bin/python3.6 .env3 --system-site-packages
- Activate it:
. .env3/bin/activate
- Create environment:
-
Install dependencies. If you want to convert models only from particular framework, you should use one of available
requirements_*.txtfiles corresponding to the framework of choice. For example, for Caffe userequirements_caffe.txtand so on. When you decide to switch later to other frameworks, please install dependencies for them using the same mechanism:pip3 install -r requirements.txt
Or you can use the installation scripts from the "install_prerequisites" directory.
-
[OPTIONAL] If you use Windows OS, most probably you get python version of
protobuflibrary. It is known to be rather slow, and you can use a boosted version of library by building the .egg file (Python package format) yourself, using instructions below (section 'How to boost Caffe model loading') for the target OS and Python, or install it with the pre-built .egg (it is built for Python 3.4, 3.5, 3.6, 3.7):python3 -m easy_install protobuf-3.6.1-py3.6-win-amd64.egg
It overrides the protobuf python package installed by the previous command.
Set environment variable to enable boost in protobuf performance:
set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp
Setup development environment
