Loads a shared library from the given path into the current process.
|
||
|
|
|
||
|
|
The library being loaded may run global initialization code to register
|
||
|
|
custom classes with the PyTorch JIT runtime. This allows dynamically
|
||
|
|
loading custom classes. For this, you should compile your class
|
||
|
|
and the static registration code into a shared library object, and then
|
||
|
|
call ``torch.classes.load_library('path/to/libcustom.so')`` to load the
|
||
|
|
shared object.
|
||
|
|
|
||
|
|
After the library is loaded, it is added to the
|
||
|
|
``torch.classes.loaded_libraries`` attribute, a set that may be inspected
|
||
|
|
for the paths of all libraries loaded using this function.

|

path (str): A path to a shared library to load.
