omegaconf.errors.ConfigKeyError: str interpolation key 'optimization.lr' not found

I don’t know how to solve this error: " omegaconf.errors.ConfigKeyError: str interpolation key ‘optimization.lr’ not found" Here is the command i’m running:

Code

fairseq-train data-bin/XXXX/ --save-dir XXXX --arch lstm --encoder-bidirectional --encoder-layers 2 --decoder-layers 2 --dropout 0.2 --lr 5e-4 --batch-size 32 --optimizer adam --eval-bleu --eval-bleu-args ‘{“beam”: 5, “max_len_a”: 1.2, “max_len_b”: 10}’ --eval-bleu-detok moses --best-checkpoint-metric bleu --maximize-best-checkpoint-metric

I’ll appreciate your help.

What have you tried?

I checked that i have the optimizer and learning rate in the command.

Hi Myleott, I uninstalled the previous version and reinstalled omegconf==2.0.5 hydra-core==1.0.4 and it works fine now. Thank you so much
