To use LightningDataModule, you have to use latest master or RC release.
You can install RC release with pip install pytorch-lightning==0.9.0rc2

Is this version also available on conda somehow?

@samiede, I'm not sure if this 100% meets your needs (and I apologize if this is something you already know), but I was able to use conda to work around (but not truly solve) the problem of using conda to install pytorch-lightning by using pip inside my conda environment.

In particular, I ran conda env create in a directory with an environment.yml that looked like this:

name: myenv
dependencies:
  - python=3.7
  - more-itertools
  - conda-forge::typing_extensions
  - pandas
  - matplotlib
  - pytorch==1.4.0
  - pip
  - pip:
    - transformers
    - pandarallel
    - pytorch-lightning==0.9.0rc2
