Failed to run

Can anyone help me fix this error?

$ xmanager launch ./xmanager/examples/cifar10_tensorflow/launcher.py
...
TypeError: 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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

I put protobuf==3.20.* in ./xmanager/requirements.txt, but it did not fix the issue.

We rebuilt the protos with protoc 3.21

How can I fix this error?

[Andrew Chen]

Are you running from HEAD? If you clone the repository and install the package, the protos should be up to date and you don't get the error.

This is what I did:

$ pip show protobuf
Name: protobuf
Version: 4.22.0

$ git clone https://github.com/deepmind/xmanager

$ xmanager launch ./xmanager/examples/cifar10_tensorflow/launcher.py
...

Did you re-install the package? Do pip uninstall xmanager and pip install ./xmanager

[Qingyao Sun]

Can you push a new release to PyPI? People should avoid installing HEAD since it's generally unstable.

Newer releases will use features of Python3.10
