# NOTE: we have to import python protobuf here **before** we load cpp extension.
|
|
# Otherwise it breaks under certain build conditions if cpp implementation of
|
|
# protobuf is used. Presumably there's some registry in protobuf library and
|
|
# python side has to initialize the dictionary first, before static
|
|
# initialization in python extension does so. Otherwise, duplicated protobuf
|
|
# descriptors will be created and it can lead to obscure errors like
|
|
# "Parameter to MergeFrom() must be instance of same class:
|
|
# expected caffe2.NetDef got caffe2.NetDef."
|
|
#
|
|
# This has to be done for all python targets, so listing them here
