issue in creating TRG_MAPPED.EMB file

[asha2785]

Recently when I was trying vecmap using following command
!python3 map_embeddings.py --unsupervised wiki.sa.vec.txt wiki.kn.vec.txt SRC_MAPPED.EMB TRG_MAPPED.EMB

I observed that this command is creating only SRC_MAPPED.EMB file.
TRG_MAPPED.EMB was empty by showing the following error
Error! OK
Saving Disabled
See console for more details.

Kindly help me.
