installation failed (Ubuntu and MacOS)

[konstantin-korovin]

Hello,

I tried to install ocaml-torch on Ubuntu and MacOS (M1) in different ways but all failed.
Any tips would be highly appreciated.

Thanks,
Konstantin

=====
Ubuntu 22.04.2 LTS

-- using opam (tried: ocaml 5.2.1, , 5.1.1+flambda, 5.1.0, 4.14.1+flambda)

> opam switch
5.2.1                      ocaml-base-compiler.5.2.1,ocaml-options-vanilla.1

 ---------- 
 It seems that libtorch installed by opam is not compatible with ocaml-torch.

 I installed libtorch version 2.3.0 in a local directory and specified path via
 export LIBTORCH="..."

=> Installation of ocaml-torch failed. This likely happened
   because there is no system installation of libtorch to compile
   OCaml bindings against. Please instal the CPU version of libtorch
   through opam, or the appropriate version of libtorch for your GPU
   through the official distribution.

I tried different OCaml releases ( ocaml 5.2.1, , 5.1.1+flambda, 5.1.0, 4.14.1+flambda) with similar errors.

[mwlon]

I think 0.17.0 was broken, but 0.17.1 should work. Can you try your second method (setting the LIBTORCH env var to a local directory), opam update, unpin torch if necessary, and reinstall v0.17.1 specifically?

[konstantin-korovin]

Thanks @mwlon.

===========
It picks up correct libtorch paths and torch.h is in
