A bug in the readme file

In the example code, you forgot to put {} around the "string:Bconfig()" pair.

Right now:
bmodel = prepare_binary_model(model, bconfig, custom_config_layers_name=['conv1' : BConfig()])

Should be:
bmodel = prepare_binary_model(model, bconfig, custom_config_layers_name=[{'conv1' : BConfig()}])

The issue points to a syntax error in the README file. Locate the README.md in the repository root, find the example code for prepare_binary_model, and correct the dictionary syntax by adding curly braces around 'conv1' : BConfig(). Verify the fix by checking the formatting and ensuring no other similar errors exist in the file.
