How could I use word-level ELMO easily?

[ricky9123]

It's easy to train a word-level ELMO by this repo, and I could remove char_cnn parameter to achieve this.

However, when I used this ELMO in allennlp, I found that it doesn't support word-level ELMO because it will always find the char_cnn parameter.

Did I have something wrong?

Some key logs are following:

And my ELMO config is:

{"bidirectional": true, "dropout": 0.1, "lstm": {"cell_clip": 3, "dim": 4096, "n_layers": 2, "proj_clip": 3, "projection_dim": 512, "use_skip_connections": true}, "all_clip_norm_val": 10.0, "n_epochs": 10, "n_train_tokens": 21150, "batch_size": 128, "n_tokens_vocab": 21150, "unroll_steps": 20, "n_negative_samples_batch": 8192}

allennlp use both word and char embedding
