TypeError: Can't instantiate abstract class Euclidean with abstract methods get_metric, score_pairs

Hi, thank you for nice work. I am getting the following error when I run source_train.py.

Files already downloaded and verified Market1501 dataset loaded subset | # ids | # images

I also got the same error.

Any way to resolve the error?

Hi, this reposity uses metric_learn 0.3.0. It this the same with your settings?

I used 0.2.0,0.3.0, or 0.4.0 to run and got another error :ImportError: cannot import name 'graph_lasso'

And if I use 0.5.0, 0.6.0, I still got error same as title.

I fixd it as follow step scikit-learn 0.20.0 metric-learn 0.4.0
