Error when load Pytorch

Here is my pom.xml：

        </dependency>

My code is：

Engine engine = Engine.getEngine("PyTorch");

My Error is：

Shoud I installed Pytorch on my computer before using DJL?

[frankfliu]

DJL doesn't depend on python and PyTorch. Why it try to load files from: E:\Anaconda3\Lib\site-packages\torch\lib\asmjit.lib? Did you send PYTORCH_LIBRARY_PATH env var?

By the way, your dependencies in your POM file is messed up.

1. you version is mismatched between DJL's libraries, see: https://docs.djl.ai/master/engines/pytorch/pytorch-engine/index.html#supported-pytorch-versions
2. Can you use latest DJL, 0.18.0 is very old
3. Please use BOM to manage DJL's dependency: see: https://docs.djl.ai/master/bom/index.html#djl-bill-of-materials-bom
