yaml.scanner.ScannerError: while scanning a simple key about lichess-bot

[ShailChoksi]

Sorry guys, the default was mistyped:

engine:                   # engine settings
  dir: "./engines/"         # dir containing engines, relative to this project
  name: "engine_name"        # binary name of the engine to use
#  weights: "latest.txt"     # only if the engine is lczero
#  threads: 1                # only if the engine is lczero

Notice I removed {} and added :

start again from config.yml.default

With latest master:

[gbtami]

Is there any reason using yaml instead of python built in configparser module?

[ShailChoksi]

@gbtami No reason. I wasn't aware of configparser and have used yamls before.
