Load Pretrained Model

You can use this model by installing torch or tensorflow and Huggingface library transformers . And you can use it directly by initializing it like this:

from transformers import BertTokenizer, BertModel

model = BertModel.from_pretrained('malay-huggingface/bert-base-bahasa-cased')
tokenizer = BertTokenizer.from_pretrained(
    'malay-huggingface/bert-base-bahasa-cased',
    do_lower_case = False,
)

Example using AutoModelWithLMHead

from transformers import BertTokenizer, BertForMaskedLM, pipeline

model = BertForMaskedLM.from_pretrained('malay-huggingface/bert-base-bahasa-cased')
tokenizer = BertTokenizer.from_pretrained(
    'malay-huggingface/bert-base-bahasa-cased',
    do_lower_case = False,
)
fill_mask = pipeline('fill-mask', model=model, tokenizer=tokenizer)
fill_mask('Permohonan Najib, anak untuk dengar isu perlembagaan [MASK] .')

Output is,
