诗诗安装tensorflow失败

Question

我有一个诗歌项目。我的环境是 Windows 机器上的 Conda 22.9.0，诗歌版本为 1.2.2：

\n

这是我的 pyproject.toml 文件：

\n

[tool.poetry]\nname = "myproject"\nversion = "0.1.0"\ndescription = ""\n\n[tool.poetry.dependencies]\n# REVIEW DEPENDENCIES\npython = ">=3.7,<3.11"\nnumpy = "*"\ntensorflow = "^2.8"\n\n[build-system]\nrequires = ["poetry>=0.12"]\nbuild-backend = "poetry.masonry.api"\n\n[tool.poetry.scripts]\nstart = "myproject.main:start"\n

\n

myproject\\main.py 模块包含：

\n

import tensorflow as tf\n\ndef start():\n    if tf.test.is_gpu_available():\n        print("TensorFlow is using a GPU.")\n    else:\n        print("TensorFlow is NOT using a GPU.")\n

\n

如果我这样做poetry install，它似乎工作正常：

但是执行时poetry run start我在导入时出错

Answer 1

对于处理错误消息的任何人：

Unable to find installation candidates for tensorflow-io-gcs-filesystem (0.32.0)

这是因为版本与您尝试安装的tensorflow版本不兼容（请参阅此处的兼容性）。例如，如果您尝试安装tensorflow 2.10.*，则需要在.toml 文件中显式定义tensorflow-io-gcs-filesystem 的适当版本（即tensorflow-io-gcs-filesystem = "0.27.0"）。

然后继续下载tensorflow（即poetry add tensorflow@~2.10）

Answer 2

我可以确认对于 TF 2.11 这确实是一个问题。无法给您明确的答案为什么这不再起作用，但它似乎与元数据相关。正如评论中已经提到的，Pip 安装它没有任何问题。

2.10 仍然适用于诗歌，但这没什么帮助。
