### 2026-05-07 — Torch.jl MLP forward retry (criterion 4)
|
||||||
|
|
||||||
|
Path: `experiments/julia_torch_mlp/`.
|
||||||
|
|
||||||
|
Torch.jl was tested as a possible replacement for Flux/CUDA on the same
|
||||||
|
DeepCFRMLP forward benchmark. The measurement could not start because
|
||||||
|
Torch.jl v0.1.3 fails during package load/precompile on this Julia
|
||||||
|
1.11.9 environment:
|
||||||
|
|
||||||
|
```text
|
||||||
|
UndefVarError: libtorch_c_api not defined in Torch.Wrapper
|
||||||
|
```
|
||||||
|
|
||||||
|
This occurs before model construction or timing, so there is no
|
||||||
|
Torch.jl forward result to compare against PyTorch.
|
||||||
|
|
||||||
|
**Verdict on criterion 4 after Torch.jl retry:** unchanged FAIL. Flux.jl
|
||||||
|
misses the performance threshold, and Torch.jl is blocked by package
|
||||||
|
load failure rather than providing a successful re-measurement.

# Julia Torch MLP Forward Benchmark
|
||||||
|
|
||||||
|
Attempted Criterion 4 re-measurement using Torch.jl for the same
|
||||||
|
`DeepCFRMLP` shape used in `experiments/julia_flux_mlp/`:
|
||||||
|
|
||||||
|
- input dim: 365
|
||||||
|
- hidden size: 512
|
||||||
|
- hidden layers: 3
|
||||||
|
- output dim: 22
|
||||||
|
- activation: ReLU
|
||||||
|
|
||||||
|
Run:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
tools/julia/current/bin/julia --project=experiments/julia_torch_mlp \
|
||||||
|
experiments/julia_torch_mlp/bench_torch.jl
|
||||||
|
```
|
||||||
|
|
||||||
|
## Result (2026-05-07)
|
||||||
|
|
||||||
|
Torch.jl could not be loaded on this host:
|
||||||
|
|
||||||
|
```text
|
||||||
|
Torch.jl v0.1.3 failed to precompile:
|
||||||
|
UndefVarError: libtorch_c_api not defined in Torch.Wrapper
|
||||||
|
```
|
||||||
|
|
||||||
|
This happens before any model construction or timing is possible, so no
|
||||||
|
DeepCFRMLP forward benchmark could be run.
|
||||||
|
|
