# tensorplay.cuda.tunable.read_file Source: https://www.tensorplay.cn/docs/generated/tensorplay.cuda.tunable.read_file.html ```python tensorplay.cuda.tunable.read_file(filename: str | None = None) → bool ``` Merge a tuning results file into the in-memory database. The file’s validator lines must match the current build and device; otherwise the file is rejected and False is returned. Entries already measured in this process win over the file’s. If filename is not given, the configured results file is used.
