Python Bindings Reference - Stable¶
Version 0.21.8922
Getting Started¶
Start by downloading the correct version of the python bindings library.
Note, the CPU python bindings library contains the static SDK library (so you do not need to download libtf.a library separately).
If using the GPU python bindings library, then you will require both the python bindings library as well as libtf.so (both are packaged in the download zip).
Ensure that libtf.so is in your LD_LIBRARY_PATH. You can confirm this by running ldd on the bindings library and ensuring that all dependencies are met.
The SDK must first be configured to your desired settings. Consult the general section for the various configuration options.
