尝试使用 pixi 从 pypi 安装 eif 时出现“没有名为 numpy 的模块”

Question

我正在尝试将

pixi

用于 python 库，并且在尝试安装 pipy 依赖项

eif

时遇到错误。

~/code> pixi init test-pixi-eif --format pyproject
✔ Created /home/oliver/code/test-pixi-eif/pyproject.toml
~/code/test-pixi-eif> cd test-pixi-eif/
~/code/test-pixi-eif> pixi add numpy
✔ Added numpy >=2.1.3,<3
~/code/test-pixi-eif> pixi add --pypi eif

对应的

pyproject.toml

文件为：

[project]
authors = [{name = "foo", email = "bar"}]
description = "Add a short description here"
name = "test-pixi-eif"
requires-python = ">= 3.11"
version = "0.1.0"
dependencies = ["eif>=2.0.2,<3"]

[build-system]
build-backend = "hatchling.build"
requires = ["hatchling"]

[tool.pixi.project]
channels = ["conda-forge"]
platforms = ["linux-64"]

[tool.pixi.pypi-dependencies]
test_pixi_eif = { path = ".", editable = true }

[tool.pixi.tasks]

[tool.pixi.dependencies]
numpy = ">=2.1.3,<3"

我也尝试过将

eif

放在

[tool.pixi.pypi-dependencies]

下，而不是先安装

numpy

，但这似乎没有什么区别。

令我困惑的是，当我在 micromamba/conda 环境中手动安装 numpy 时，然后

pip install eif

，我没有遇到任何问题。我认为 pixi 的做法本质上是一样的，但一定有什么地方不同。

Answer 1

看起来缺少 numpy 包。如果是这样，请通过

安装numpy

pip install numpy

您可以在添加 eif 之前在 Pixi 环境中显式预安装 numpy。您可以先显式添加 numpy：

pixi add numpy

numpy后面加上eif：

pixi add --pypi eif

我希望这些步骤能够解决问题。既然您喜欢机器学习项目，您也可以看看这个：https://www.pcbway.com/project/shareproject/IoT_AI_driven_Smart_Grocery_Cart_w_Edge_Impulse_5652a9b2.html
