Do you have AI::MXNet running?

The_Dj has asked for the wisdom of the Perl Monks concerning the following question:

Update: Solved!

see my reply below

Greetings Monks and lurkers.

I had a system update break my MXNet installation a while back.
Sadly it's been long enough that I don't recall the exact magic combination of OS/mxnet/perl/ai::mxnet/phase of moon/sacrificial gpu/other That I'd used to get it running.

If anyone has a currently working installation of AI::MXNet, please let me know what version of all these things is the magic mix I need to replicate.

Alternately, I did consider witching to AI::TensorFlow, but I haven't been able to figure out how to train a new model...
all the sample code uses pre-trained networks and I just can't figure out the (too deep for me) magic to train a new network. I'd be more than happy with a simple 'Hello world' (MNIST handwriting) demo if anyone has something to hand.

Thanks :-)

    Apache MXNet moved into the Attic in 2023-09. Apache MXNet was a flexi +ble and efficient library for Deep Learning.

    however that does not mean you can not install it, if you are on linux perhaps download its source tarball ( ) and see where that takes you. I am doing the same now on my linux box (latest fedora).

      Hi, Anon

      Thanks, I know that it's been retired, But until I can figure out AI::TensorFlow, it's the best I can get. (AI::FANN is just too slow)

      I've tried the source tarball- getting it to compile is a headache in itself.
      But then AI::MXNetCAPI (a prereq) can't build because the signature for MXOptimizeForBackend in c_api.h differs wildly from the parameters passed in mxnet_wrap.cxx


        a real pain!

        the signature for MXOptimizeForBackend in c_api.h differs wildly from the parameters passed in mxnet_wrap.cxx

        I have solved that by updating the signature in mxnet.i to what c_api.h has. But I still don't know until the other dependency AI::NNVMCAPI compiles. If that hack does not solve it then we can try wrap the new signature with the old one.

        Right now, AI::NNVMCAPI requires tvm, as you mentioned. My last attempt is getting tvm from the git repository (, install Intel mkl, dnnl etc. and see. There are problems right now with tvm compilation as I have encountered this: because I have set DNNL ON.

        All in all, it seems Apache have created millions of lines of code which are so smelly with bitrot is unbearable. Is the attic the right place or the cold ground instead?

    Here is the short verson:
    MXNet up to version 1.9.1 was written for cuda 11. It is not compatible with cuda 12
    MXNet 2.0.0 with cuda12 compatability was retired before it was stable

    There was a Docker container on the HUB that ran mxnet, but it's gone now
    There is a Docker container that includes the cuda 11 and cudnn8 development 'stuff'

    For your convenience*, here is a Dockerfile that will** build an image with working AI::MXNet 1.9.0 (1.9.1 doesn't work)
    (And some tips for those who don't use docker. I'm far from expert, but what I've put here is at least correct at the time of writing)
    Build with docker buildx build -t perlmx .*3 The final image is 18GB and can take hours to build :-(
    Run with docker run --runtime=nvidia --gpus=all -it perlmx*4 to get a root prompt. You can then also ssh -X mxnet@*5*6*7 to get X11
    Or run with docker run --runtime=nvidia --gpus=all -dit perlmx to detach and then ssh -X mxnet@*7 *8
    (If you are new to Docker, read up on the run, start, stop, ps -a and images commands, or you will loose your work, suck up all your disks or both)

    You could also use the information and magic versions below to build a bare-metal (or other VM) server if you want. I'm not going to tell you what to do.

    Good Luck

    ** You need to install the NVIDIA Container Toolkit if you want to actually use your GPU.
    *3 If you are new to docker: Just install docker (v23 or later) and it should just work
    *4 If you don't want to use your GPU, don't have a compatible GPU or couldn't get the NVIDIA container toolkit to work, run with docker run -it perlmx or docker run -dit perlmx and make your CPU do all the things.
    *5 Password is mxnet.
    *6 Your IP may vary.
             When you first launch the container interactively (with -it), it displays its IP address.
             You can also use docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id on a running container
    *7 You can also not use -X if you don't want/need X11 support.
    *8 User mxnet is in sudoers, so...

    FWIW: I'm running the docker service in kali linux in WSL2, with an nVidia 2080 Super. YMMV
