@manuEbg can you try:

const libknet8 = Libdl.find_library(["libknet8"], try [artifact"libknet8"]; catch ex; []; end)

Hey @denizyuret , I am very sorry, but I absolutely lost track of this one.

I just noticed you implemented the suggested solution with 553a5b6 .

However I still get

Dear @manuEbg: The libknet8 library is only needed if you want to use the GPU. As far as I know this is not possible with the Macs at the moment as CUDA.jl no longer supports them. Do you just want a clean install for cpu use only?

from knet.jl.

manuEbg avatar manuEbg commented on May 29, 2024

Hey @denizyuret,
thank you very much for you're reply!
Yes I only want to get started with julia and Knet and wanna do some basic Learning Stuff inside a clean docker-container.
No need for GPU-Acceleration at this point:)
So is there a way to install knet without GPU-support?

from knet.jl.

denizyuret avatar denizyuret commented on May 29, 2024

@maleadt: we seem to have a problem in Knet where the installation gets stuck on a new architecture with no gpu support because it cannot locate the libknet8.so artifact. In these cases we want the installation to proceed with no libknet8. Thinking that you may have had a similar problem in CUDA.jl and its artifacts I wanted to pick your brain -- do you have any suggestions?

from knet.jl.

Wrap the (function that calls the) artifact macro in try/catch? https://github.com/JuliaGPU/CUDA.jl/blob/e1ba6121e4d32a5d90b6f1849926e9b4f0062700/deps/bindeps.jl#L95-L100

@manuEbg can you try:

const libknet8 = Libdl.find_library(["libknet8"], try [artifact"libknet8"]; catch ex; []; end)

from knet.jl.

manuEbg avatar manuEbg commented on May 29, 2024

This also falls into the same error.
It does not really make sense to me.

try 
     tempLibVar = Libdl.find_library(["libknet8"],[artifact"libknet8"])
catch ex 
     print("I catched the Exception");
end

from knet.jl.

I did some more test.

try
    artifact"notExistent"
catch ex
    print("Got it")
end

try
    platform = Base.BinaryPlatforms.HostPlatform()
    rand(4,4) * rand(5,5)
    @artifact_str("notExistent", platform)
catch ex
    print("Got it: $ex")
end

Both of the above result in :

However this one:

try
    platform = Base.BinaryPlatforms.HostPlatform()
    rand(4,4) * rand(5,5)
    # @artifact_str("notExistent", platform)
catch ex
    print("Got it: $ex")
end

results in:

Got it: DimensionMismatch("A has dimensions (4,4) but B has dimensions (5,5)")

I think this behaviour is very strange

Same issue on FreeBSD:

LoadError: Cannot locate artifact 'libknet8' for x86_64-unknown-freebsd-libgfortran5-cxx11-julia_version+1.7.3 in '/.julia/packages/Knet/YIFWC/Artifacts.toml'

https://cirrus-ci.com/task/6610845332406272?logs=test#L201

All seems well on the GitHub Actions VMs (Ubuntu, macOS and Windows64), even though I imagine they don't have a GPU either.
