## Q: The WikiText dataset download link is not available.
A: The official download link is not available, please follow the community Issue [#IBV35D](https://gitee.com/mindspore/mindformers/issues/IBV35D).
## Q: How Do I Generate a Model Sharding Strategy File?
A: The model sharding strategy file documents the sharding strategy for model weights in distributed scenarios and is generally used when slicing weights offline. Configure `only_save_strategy: True` in the network `yaml` file, and then start the distributed task normally, then the distributed strategy file can be generated in the `output/strategy/` directory. For details, please refer to the [Tutorial on Slicing and Merging Distributed Weights](https://www.mindspore.cn/mindformers/docs/en/master/feature/ckpt.html).
## Q: How Can I Do When `socket.gaierror: [Errno -2] Name or service not known` or `socket.gaierror: [Errno -3] Temporary failure in name resolution` is Reported in `ranktable` Generation File?
A: Starting from `MindSpore Transformers r1.2.0` version, cluster startup is unified using `msrun` method, and `ranktable` startup method is deprecated.
## Q: When installing MindSpore Transformers from source code, the download speed of dependency packages is slow. How can this be resolved?
A: The `build.sh` script uses the [Tsinghua Mirror](https://mirrors.tuna.tsinghua.edu.cn/help/pypi/) to download the Python packages required by MindSpore Transformers. To change the mirror source, you can modify the download command in `build.sh`: `pip install mindformers*whl -i https://pypi.tuna.tsinghua.edu.cn/simple` , replace the URL after `-i` with the address of your desired mirror source.
