Local references fail in lambda functions #25
Description
Describe the bug
Local references using @ fail when used in a lambda function and executed using "$". Here are examples that I have encountered:
the python object are defined like this in the top level of json:
"data_dir": "/dataset/pathology/images/",
"patch_size": [
224,
224
]and used like this in train and validate sections:
"transform": {
"_target_": "Lambdad",
"keys": "image",
"func": "$lambda x: os.path.join(@data_dir, 'training/images', x + '.tif')"
}
"transform": {
"_target_": "Lambdad",
"keys": "label",
"func": "$lambda x: x.reshape((1, *@patch_size))"
}The error that I get is
NameError: name '__local_refs' is not defined
