我正在关注关于创建自定义预测的谷歌文档（https://cloud.google.com/ai-platform/prediction/docs/custom-prediction-routines）。在为模型 AI 平台预测 API 构建新版本时抛出以下错误：
Error Create Version failed. Bad model detected with error: "Failed to load model: User-provided package <>-0.1.tar.gz failed to install: Command '['python-default', '-m', 'pip', 'install', '--target=/tmp/custom_lib', '--no-cache-dir', '-b', '/tmp/pip_builds', '/tmp/custom_code/<>.tar.gz']' returned non-zero exit status 1.

正在本地测试我的 zip 文件
pip install --target=/tmp/custom_lib --no-cache-dir -b /tmp/pip_builds dist/<>
抛出以下错误：

"""
Purpose: Package your Predictor and its dependencies by packaging Predictor as a .tar.gz.
For deploying any PyTorch model, the PyTorch package is needed to be provided in the below-mentioned command. In this case,
we have used the package:
torch-1.3.1+cpu-cp37-cp37m-linux_x86_64.whl
For getting pytorch packages according to your requirements,
Visit this link: Pytorch Packages(google search)
Download the package you require and store it in the GCS bucket.
The package we are using provides version resource with PyTorch 1.3.1 for Python 3.7, built to run on a CPU in Linux.
NOTE: We could have directly added ‘torch’ in the ‘REQUIRED_PACKAGES’ list in setup.py file in order to provide pytorch as a dependency to be installed while deployment.
This way, it uses the PyPI installation of pytorch.
But the issue with this approach is that it internally downloads PyPI package for pytorch which is of 720 MB Which causes the failure of our model deployment because the AI platform allows custom models of 500MB or below to be deployed on it.
So it is recommended to provide a pytorch package manually using gsutil command under — package-uris.
Try: pip install --target=/tmp/custom_lib --no-cache-dir -b /tmp/pip_builds <>.4.tar.gz for troubleshooting

Have tried the usual upgrading python setuptools to 52.0.0, but can't seem to shake this error off.
