Re: [julia-users] Re: static compilation

It looks like there might be a parser ambiguity when the arguments are given as a tuple (the whole thing is parsed as keyword argument to the macro call). Either of the following will work right now: @Base.ccallable Int64 foo(x::Int64) = x+1 @Base.ccallable(Int64, function foo(x::Int64)

Re: [julia-users] tensor flow question

Several things seem to be happening here: - TensorFlow.jl does not export `tanh` (but does export `tanh_`, note underscore) - There is ambiguity among several `sigmoid` method signatures, which may cause the import to fail (try calling `TF.API.sigmoid` directly to see the warning). - Julia does

Re: [julia-users] uv-unix.h not found on windows

How did you install Julia? The issue is that the compiler is incorrectly identifying as unix, so libuv looks for headers which are not available. You could try compiling with `gcc ... -mwin32`. But most likely you will need to get a supported toolchain. See the windows build instructions:

You could try uploading files to your own AWS bucket and access them using AWS.jl. (I don't know what the transfer speed / latency would be like). SageMathCloud supports Julia (or did in the past; not sure about current version), and they have a generous free account (3 GB). Their subscription is

Use `@__LINE__` and `@__FILE__`. (note, however, `@__LINE__` does not work when used within another macro, see https://github.com/JuliaLang/julia/issues/9577) On Tue, May 10, 2016 at 6:25 AM, FANG Colin wrote: > Currently I am using > > macro markup(line_number) >
