I am trying to run this reading-text-in-the-wild on Mac M1. When I attempt to run this code
python3 make_keras_charnet_model.py
I get the error
Using Theano backend.

I have duplicated my terminal to have the duplicate open with Rosetta and still I get the error.
when I run the command below to check the architecture available on my M1 Mac
file /bin/bash
I get this output
/bin/bash: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64e:Mach-O 64-bit executable arm64e]
/bin/bash (for architecture x86_64): Mach-O 64-bit executable x86_64
/bin/bash (for architecture arm64e): Mach-O 64-bit executable arm64e
I looks like I have both x86_64 and arm64e available but the error is saying
(mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/local/lib/cutils_ext.so' (no such file), '/usr/lib/cutils_ext.so' (no such file)
what is causing this error and how can I fix it?
I found that i need to specify the architecture
so instead of
python3 make_keras_charnet_model.py
i now use this
arch -arm64 python3 make_keras_charnet_model.py
