Web.lua does not work

[slayerduck]

Successfully installed everything, i can use the command line to convert images but the web gui errors out

[root@waifu2x waifu2x-master]# th web.lua

try upgrade luajit version to 2.0.4.
http://luajit.org/download.html

[slayerduck]

I'm already running 2.0.4

hmm.. seems turbo.lua failed to detecting your platform.
maybe following patch fixes this issue.
edit file: turbo/turbo/platform.lua (https://github.com/kernelsauce/turbo/blob/master/turbo/platform.lua#L30)

    __ABI32__ = false, -- true if your platform is i386
    __ABI64__ = true, -- true if your platform is x86-64

and reinstall.
if you need more support, please create a issue in turbo (https://github.com/kernelsauce/turbo)

After changing that and recompiling i get this:

/root/torch/install/bin/luajit: /root/torch/install/share/lua/5.1/trepl/init.lua:363: /root/torch/install/share/lua/5.1/trepl/init.lua:363: /usr/local/share/lua/5.1/turbo/util.lua:351: Could not load libtffi_wrap
Please run makefile and ensure that installation is done correct.

I am getting this (Could not load libtffi_wrap) too.

[nagadomi]

try

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
th web.lua

[slayerduck]

Works, can be closed thanks!

TIP for other people facing this issue: add the line export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib to your .bashrc

I met the error Could not load libtffi_wrap

try

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
th web.lua

This doesn't work on my case.

My Env:

• CentOS 7.3
• GPU V100 with driver 410.129
• CUDA 10

After I install turbo with luarocks, the output is :

==== Installing libtffi_wrap ====
test -f libtffi_wrap.so && \
install -m 0755 libtffi_wrap.so /home/work/torch/install/lib/libtffi_wrap.so.2.1.0 && \
ldconfig -n /home/work/torch/install/lib && \
ln -sf libtffi_wrap.so.2.1.0 /home/work/torch/install/lib/libtffi_wrap.so
==== Successfully installed Turbo.lua 2.1.0 to /home/work/torch/install ====
Updating manifest for /home/work/torch/install/lib/luarocks/rocks
turbo 2.1-2 is now built and installed in /home/work/torch/install/ (license: Apache 2.0)

I notice that my libtffi_wrap.so was located in $HOME/torch/install/lib not /usr/lib

Run

~/torch/install/bin/torch-activate

This script adds ~/torch/install/lib to LD_LIBRARY_PATH.
Also, this script is registered in ~/.bashrc or ~/.zshrc when installing torch, so it will be automatically applied once you login again.

Thanks
