This feature column can be used on an input feature whose values are strings of arbitrary size.
hub_text_embedding_column(key, module_spec, trainable = FALSE)
A string or [feature_column](https://tensorflow.rstudio.com/tfestimators/articles/feature_columns.html) identifying the text feature.
A string handle or a _ModuleSpec identifying the module.
Whether or not the Module is trainable. `FALSE` by default, meaning the pre-trained weights are frozen. This is different from the ordinary `tf.feature_column.embedding_column()`, but that one is intended for training from scratch.
