# 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_device_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 == AmdSmiRetCode.ERR_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.
