Workaround for the 'axis' error on OpenVINO™ toolkit 2020.1 and 'Aborted' error on OpenVINO™ toolkit 2020.2 and 2020.3 while running inference on Raspbian OS.
Issue on 2020.1
Error trying to run inference in the OpenVINO™ toolkit 2020.1 version using Raspberry pi.
Error encountered:
RuntimeError: Check 'axis < static_cast(input_rank)' failed at /teamcity/work/scoring_engine_build/releases_2020_1/ngraph/src/ngraph/op/gather.cpp:140: While validating node 'Gather[Gather_1718](patternLabel_1714: float{10,20,30}, patternLabel_1715: int64_t{5}, patternLabel_1717: int64_t{1}) -> (??)': The axis must => 0 and <= input_rank (axis: 4294967295)
Issue on 2020.2 and 2020.3 versions:
terminate called without an active exception
Aborted
These errors are caused when using the new IR format on Raspbian OS.
Option 1:
Generate the IRv7 format files using the Model Optimizer from the full installation of OpenVINO™ toolkit with the following parameter: --generate_deprecated_IR_V7.
Option 2:
Use the previous pre-trained models from the open model zoo.
Option 3:
Install the previous version of OpenVINO™ toolkit (2019 R3.1) on a Windows*, Linux*, or macOS* system, convert the model there, which will generate the IR v7 format.
| Note |
The 'axis' bug has been fixed in the Intel® Distribution of OpenVINO™ toolkit v2020.2 for Raspbian OS. Fixes have been addressed in the Intel® Distribution of OpenVINO™ toolkit v2020.4. Update your software to the latest version and use the latest version IR files, as the older ones are not compatible with the latest releases. |
