Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("ANGKJ1995/all-MiniLM-L6-v2-job-description")
# Run inference

    'Composer/Orchestrator writes musical compositions such as symphonies, sonatas or operas. He/she translates compositions into standard musical signs and symbols on scored music paper. He/she may write words to accompany music. He/she adapts melodies to suit the type and style of orchestras or bands and to produce various kinds of effects. He/she determines instruments to be employed, writes musical scores to produce the desired musical effect, rewrites music written for one instrument or purpose into suitable forms for other instruments or purposes.',
    'Conduct, direct, plan, and lead instrumental or vocal performances by musical artists or groups, such as orchestras, bands, choirs, and glee clubs; or create original works of music.',
