You have to build the ctc_decoder. The process is available here https://nvidia.github.io/OpenSeq2Seq/html/installation.html#installation-speech

@WillemGooderham1 The installation of decoders with the following command:
bash scripts/install_decoders.sh
is failing for me with this output:
installing_decoders_output.txt
[Note: I am trying to install Baidu CTC decoder]

And while trying to run python scripts/ctc_decoders_test.pyto check installation, I run into same error as the OP.

My machine: Ubuntu 18.04

Your install is failing because you don't have swig installed on your environment (or it isn't found)

But I don't see swig mentioned in the installation documents or the requirements.txt file..

Hi,

I have windows operating system. I have installed swig and added swig to my environment path. I have ctc_decoder module but no swig_decoders. Can anyone help me where I can find it?
