JSON issues with 'kernel_ridge_SCM_OFM' example #54

Open dptru10 opened 5 years ago

dptru10 commented 5 years ago

The 'kernel_ridge_scm_ofm' example script produces the following error when trying to load the 'flla' dataset:

REMOVE UNSTABLE ENTRIES: False USE FABER DATASET: True USE TERNARY OXIDE DATASET: False NUMBER OF JOBS: 24 DEBUG MODE: False Traceback (most recent call last): File "kernel_ridge_SCM_OFM.py", line 67, in df = load_dataset("flla") File "/home/dennis/.local/lib/python3.5/site-packages/matminer/datasets/dataset_retrieval.py", line 63, in load_dataset df = load_dataframe_from_json(data_path) File "/home/dennis/.local/lib/python3.5/site-packages/matminer/utils/io.py", line 58, in load_dataframe_from_json dataframe_data = json.load(f, cls=MontyDecoder) File "/usr/lib/python3.5/json/init.py", line 268, in load parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw) File "/usr/lib/python3.5/json/init.py", line 312, in loads s.class.name)) TypeError: the JSON object must be str, not 'bytes'

Any help in debugging is appreciated.

Hey @dptru10!

Thanks for the heads up, this issue must have slipped our radar. We have just updated this script in #55. We recommend using the newest version of matminer to run the script. If you still have issues with it, please open a topic on our help forum https://hackingmaterials.discourse.group
