AMD SMI Python Library

Requirements

• Python 3.6+ 64-bit

• Driver must be loaded for amdsmi_init() to pass

Overview

Folder structure

File Name	Note
__init__.py	Python package initialization file
amdsmi_interface.py	Amdsmi library python interface
amdsmi_wrapper.py	Python wrapper around amdsmi binary
amdsmi_exception.py	Amdsmi exceptions python file
README.md	Documentation

Usage

amdsmi folder should be copied and placed next to importing script. It should be imported as:

from amdsmi import *

try:
    amdsmi_init()

    # amdsmi calls ...

except AmdSmiException as e:
    print(e)
finally:
    try:
        amdsmi_shut_down()
    except AmdSmiException as e:
        print(e)

To initialize amdsmi lib, amdsmi_init() must be called before all other calls to amdsmi lib.

To close connection to driver, amdsmi_shut_down() must be the last call.

Exceptions

All exceptions are in amdsmi_exception.py file. Exceptions that can be thrown are:

• AmdSmiException: base amdsmi exception class

• AmdSmiLibraryException: derives base AmdSmiException class and represents errors that can occur in amdsmi-lib. When this exception is thrown, err_code and err_info are set. err_code is an integer that corresponds to errors that can occur in amdsmi-lib and err_info is a string that explains the error that occurred. Example:

try:
    num_of_GPUs = len(amdsmi_get_processor_handles())
    if num_of_GPUs == 0:
        print("No GPUs on machine")
except AmdSmiException as e:
    print("Error code: {}".format(e.err_code))
    if e.err_code == amdsmi_wrapper.AMDSMI_STATUS_RETRY:
        print("Error info: {}".format(e.err_info))

• AmdSmiRetryException : Derives AmdSmiLibraryException class and signals device is busy and call should be retried.

• AmdSmiTimeoutException : Derives AmdSmiLibraryException class and represents that call had timed out.

• AmdSmiParameterException: Derives base AmdSmiException class and represents errors related to invaild parameters passed to functions. When this exception is thrown, err_msg is set and it explains what is the actual and expected type of the parameters.

• AmdSmiBdfFormatException: Derives base AmdSmiException class and represents invalid bdf format.
