"value cannot be converted to type float without overflow" while using ConvS2S

I am trying to use ConvS2S and getting this error: RuntimeError: value cannot be converted to type float without overflow (-7.65404e-23,1.25e-06)

How can I handle this issue? I know there was a similar discussion on here https://github.com/OpenNMT/OpenNMT-py/issues/491 , but I don’t exactly get how to do ‘replacing ‘inf’ with 1e-18’ and if it’s right solution for my case. Thanks in advance!

my command is : CUDA_VISIBLE_DEVICES=0,1 python train.py -data conv_syllable_underbar/ -save_model conv_syllable_underbar/ -enc_layers 3 -dec_layers 3 -src_word_vec_size 512 -tgt_word_vec_size 512 -encoder_type cnn -decoder_type cnn -train_steps 200000 -max_generator_batches 2 -dropout 0.1 -batch_size 4096 -batch_type tokens -normalization tokens -accum_count 2 -optim adam -adam_beta2 0.998 -decay_method noam -warmup_steps 8000 -learning_rate 2 -max_grad_norm 0 -param_init 0 -param_init_glorot -valid_steps 100 -save_checkpoint_steps 100 -early_stopping 3 --world_size 2 --gpu_ranks 0 1

and my error is:

Does it work with other models?

Oh ok, did not notice this was a duplicate.
