I am trying to train a custom model for Czech. I followed the
instruction in README and in the FAQ, prepared my data, used the
pre-built binaries for x64 linux and was getting 'Illegal instruction'
after a few seconds without further info.

So I thought I'd go from the beginning and I installed the deepspeech
package with pip in a fresh virtualenv, I downloaded the pre-built
models and ran it as slash
deepspeech models/output_graph.pb models/alphabet.txt models/lm.binary
models/trie data/smoke_test/LDC93S1.wav slash
Again, I got Illegal instruction.

I was trying on these machines (uname -a) slash

can you share cat /proc/cpuinfo ?

run deepspeech -h and check the requested position of the wav file

No AVX, as confirmed by
https://ark.intel.com/products/35562/Intel-Core2-Duo-Processor-T9400-6M-Cache-2_53-GHz-1066-MHz-FSB?q=T9400

You'll have to rebuild with --copt=-march=native to target your CPU,
but with not even SSE4.2 I don't know how much performances you could
expect
