Can someone help me adress this issue regarding "Failed to build fairseq" issue?

same issue, it is saying it cannot build wheel during the faireseq

Install Microsoft Visual C++ Build Tools:

Go to the Visual Studio downloads page. Or maybe you already have Visual Studio Installer on your CPU? Open it. I use Visual Studio Community 2019 If you have it already click modify. Download and install the "Build Tools for Visual Studio" if you don't have it. During installation, under "Workloads", select "C++ build tools" and ensure the latest versions of "MSVCv142 - VS 2019 C++ x64/x86 build tools" and "Windows 10 SDK" are selected. OR go to individual components and find those two listed Complete the installation.

Reinstall the Dependencies:

After installing the Visual C++ Build Tools, try installing the dependencies again. Make sure you're in the rvc_webui environment:

conda activate rvc_webui (or whatever you called your conda env if you used one.) pip install -r requirements.txt python app.py

↑ is right. You should install vc++ first.

We're planning removing the dependency of fairseq in the next versions.

I failed to install fairseq on Windows:

build\lib.win32-cpython-310\fairseq\libbleu.cp310-win_amd64.pyd : fatal error LNK1120: 1 unresolved externals

I installed MSVC v143 - VS 2022. Did anyone succeed?

Already install "MSVCv142 - VS 2019 C++ x64/x86 build tools" and "Windows 10 SDK" but still return same

You have to install Visual Studio C++ 14.0.0 or newer

I had the same problem, running on Linux server. Whenever I tried to install fairseq I got Failed building wheel for fairseq. Aparently, the problem was in C++ compiler. Follow steps below, if you have Linux, you will just need to install g++:

1. Install / Update packages sudo apt update && sudo apt install build-essential
2. Check list of available g++ apt search '^g\+\+-[0-9]+$'
3. Install at least version 12 or later from the list of available versions sudo apt install g++-12

PS: Here are error logs I used to get before this solution

 pip install fairseq
