how can I combine 2 dataset with different/same features?
to combine 2 dataset by one-one map like ds = zip(ds1, ds2):
ds1: {'text'}, ds2: {'text'}, combine ds:{'src', 'tgt'} 
or different feature:
ds1: {'src'}, ds2: {'tgt'}, combine ds:{'src', 'tgt'}
Hi ! Currently we don't have a way to `zip` datasets but we plan to add this soon :)
For now you'll need to use `map` to add the fields from one dataset to the other. See the comment here for more info : https://github.com/huggingface/datasets/issues/853#issuecomment-727872188 Good to hear.
Currently I did not use map , just fetch src and tgt from the 2 dataset and merge them.
It will be a release if you can deal with it at the backend.
Thanks. Hi! You can rename the columns and concatenate the datasets along `axis=1` to get the desired result as follows:
```python
ds1 = ds1.rename_column("text", "src")
ds2 = ds2.rename_column("text", "tgt")
ds = datasets.concatenate_datasets(["ds1", "ds2"], axis=1)
```
