ctcdecode install fail - Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-7zcjual1/

Question

I try to install ctcdecode on ubuntu 18.04, but it is not easy.
First, I clone the repository to my server and error occurs when I 'pip install .' at the cloned root repository.
It is the guideline for installation.
git clone --recursive https://github.com/parlance/ctcdecode.git
cd ctcdecode && pip install .

Here is my error message

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-7zcjual1/

I search solution for days.
Many people recommend upgrading setuptools, but it didn't work.
How can I do to resolve my problem.
Please help. I look forward to your comment.
Thanks in advance.

Answer 1

This is likely because of an incomplete download of the boost_1_67_0.tar.gz file, as is indicated by the error message: EOFError: Compressed file ended before the end-of-stream marker was reached.

I would recommend downloading the boost file from here and replacing the ctcdecode/third_party/boost_1_67_0.tar.gz file with the complete, downloaded one. Let me know if that works!

Edit: Might be worth it to download the openfst tar as well from here and replacing the one in third_party/ as well.
