Parsing recipes...ERROR: /home/wu/3568/yocto/meta-niic/niic/recipes-support/glog/glog_0.5.0.bb: Variable PACKAGECONFIG_remove_riscv64 file: /home/wu/3568/yocto/meta-niic/niic/recipes-support/glog/glog_0.5.0.bb line: 21 contains an operation using the old override syntax. Please convert this layer/metadata before attempting to use with a newer bitbake.如何解决

这个错误是由于使用了旧的override语法导致的。要解决这个问题，您需要更新您的layer/metadata以使用新的override语法。这可以通过使用bitbake-layers update命令来完成。在您的yocto工程的根目录下运行以下命令：

bitbake-layers update <layer-name>

其中`<layer-name>`是包含`glog`的层的名称。这将更新该层的元数据并将其转换为新的override语法，以解决该错误。

train datasets not valid: Descriptors cannot not be created directly. If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately regenerate your protos, some other possible workarounds are: 1. Downgrade the protobuf package to 3.20.x or lower. 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

训练数据集无效：不能直接创建描述符。如果这个调用来自一个_pb2.py文件，你的生成代码已经过期，必须使用protoc >= 3.19.0重新生成。如果你无法立即重新生成你的protos，一些可能的解决方法是：1.将protobuf软件包降级到3.20.x或更低版本。2.设置PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python（但这将使用纯Python解析，速度会慢得多）。更多信息请参见：https://developers.google.com/protocol-buffers/docs/news/2022-05-06。
