5. Known Issues and Workarounds
Known Issues and Workarounds in Intel® FPGA AI Suite Version 2023.3
Intel® FPGA AI Suite Version 2023.2 has the following known issues:
- When an AOT (ahead-of-time) file is created by the dla_compiler on one operating system and then used with the example runtime on a different operating system, the example runtime issues an error message that states, " The model was compiled with a different version of Intel FPGA AI Suite ". For example, if you create an AOT file with the dla_compiler on Ubuntu 18 that you then try to use with the example runtime on Ubuntu 20, you receive this error message.
To resolve this error message, disable or delete lines 488 to 494 in the runtime/plugin/src/dlia_plugin.cpp file. Because this workaround disables the version check, you become responsible for ensuring that the the dla_compiler command and the example runtime have the same Intel® FPGA AI Suite version.
-
When you run the dla_benchmark example utility without specifying the -i option, the utility generates random input data. If the graph requires data in the NHWC format, the dla_benchmark utility fails to generate random input data and returns the following error message:
Unimplemented blob transformation from different shapes
To avoid this error, use the -i option to specify a directory containing at least one image for each inference request.
