It seems I had an older version (0.3.pre-np112py36_vc14_0 conda-forge [vc14]) of arrow-cpp installed. After upgrading to the current version (0.3.0.post-np112py36_vc14_1 conda-forge [vc14]), "import pyarrow" works, but "import pyarrow.parquet" fails:
{code}
$ python -c "import pyarrow.parquet"
Traceback (most recent call last):

File "C:\Users\bmachie\AppData\Local\Continuum\Miniconda3\envs\ml_recommender\lib\site-packages\pyarrow\parquet.py", line 23, in <module>

ModuleNotFoundError: No module named 'pyarrow._parquet'
{code}
parquet-cpp is installed: 1.1.0 vc14_1 [vc14] conda-forge
