# 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:

```python
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:

```python
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.
