Writing Outputs

After mining, export the ERG in any of three formats:

import ergminer

# Compute sim_time from the log
import pandas as pd
sim_time = float(
    (pd.to_datetime(log["timestamp"]).max() - pd.to_datetime(log["timestamp"]).min())
    .total_seconds()
)

ergminer.write_ergml(erg,    "output/erg.ergml", sim_time=sim_time)  # for simulation
ergminer.write_erg_json(erg, "output/erg.json")                      # full structure
ergminer.write_dot(erg,      "output/erg.dot")                       # for Graphviz

Generate an image from the DOT file with Graphviz CLI:

dot -Tpng output/erg.dot -o output/erg.png

See ergminer.write for full API details.
