there is no error. But , When I try image.display(l), I get the following error:

I have torch normal Runs, so I don’t know what will happen to qt. How can I solve this problem?

The image.display in other functions can only pass qlua Lua Interpreter access.
Calling this function from LuaJit will cause the error you encountered.
I installed the lua image according to this – link. I I also tested my installation with luajit -limage -e “image.test()”, it said 0 errors and 0 warnings. Also, when I try
> require'image'
> l = image.lena()
There is no error. However, when I try image.display(l), I receive the following error:

I have the torch running normally , So I don’t know what will happen to qt. How can I solve this problem?
Have you ever had a chance to read this?

Image.display in other functions can only be passed through qlua Lua Interpreter access.
Calling this function from LuaJit will cause the error you encounter.
