Hi,
I want to know how long it will take to train this model.
You set the epoch = 10000, and the depth of model is also twice that of Kool et-al, so I think the good results are probably due to this reason.May I ask if you have used the model of Kool et-al to do comparative experiment under the same super parameter setting?
Hello Sir, currently I am doing a project related to this. I want to ask about the minimum requirement for the gpu to do this project. Thanks for your help.
model_baseline.load_state_dict(checkpoint['model_baseline']) throws an error complaining about missing/unexpected keys. After transforming the keys from "module.start_placeholder", "module.input_emb.weight"... etc. to the form "start_placeholder", "input_emb.weight" ... in the OrderedDict, this time I get the following size mismatches:

Dear Xavier,
We read your TSP transformer paper (https://arxiv.org/abs/2103.03012) quite interesting and have some questions regarding your paper and GitHub code.
In your Github ('train_tsp_transformer_TSP50.ipythonb') code, the input x with dimension (bsz, nb_nodes, dim_input_nodes) is embedded into x with dimension (bsz, nb_nodes, dim_emb). We are wondering why this embedding process (into dim_emb dimension) is needed for the TSP problem.
