Error in eval.py

[eh102]

Hello, I want to run eval.py in HCVRP_DRL. I have followed the input instructions in the official documentation and made sure that the dataset and model are loaded correctly, and the environment matches the documentation.However, I encountered the following error message. Does anyone know how to solve it?

Traceback (most recent call last):
File "eval.py", line 226, in
eval_dataset(dataset_path, width, opts.softmax_temperature, opts)

model, _ = load_model(opts.model, opts.obj)

Hi, I have met the similar error like you. Have you solved it?

My error message:

File "...\lib\site-packages\torch\serialization.py", line 713, in load
return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args)

I changed my GPU to a 2080ti, modified the settings to the same as the official text Python 3.7, Pytorch 1.3.0. After that it worked fine with my own trained model. So I think it may be a compatibility issue with GPU, CUDA, Python, Pytroch.
