在Ubuntu22.04的Miniconda3中安装evaluate库遇版本冲突错误

问题描述 #

在Ubuntu 22.04的全新Miniconda3环境中，执行conda install evaluate时出现LibMambaUnsatisfiableError，原因是当前环境Python版本为3.12.*，而conda默认源中的evaluate包暂不支持该版本（仅兼容到Python 3.11），具体错误信息如下：

Channels:
 - defaults
Platform: linux-64
Collecting package metadata (repodata.json): done
Solving environment: - warning  libmamba Added empty dependency for problem type SOLVER_RULE_UPDATE
failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - package evaluate-0.3.0-py310h06a4308_0 requires python >=3.10,<3.11.0a0, but none of the providers can be installed

Could not solve for environment specs
The following packages are incompatible
├─ evaluate is installable with the potential options
│  ├─ evaluate [0.3.0|0.4.0] would require
│  │  └─ python >=3.10,<3.11.0a0 , which can be installed;
│  ├─ evaluate 0.3.0 would require
│  │  └─ python >=3.7,<3.8.0a0 , which can be installed;
│  ├─ evaluate [0.3.0|0.4.0] would require

│  └─ evaluate 0.4.0 would require
│     └─ python >=3.11,<3.12.0a0 , which can be installed;
└─ pin-1 is not installable because it requires
   └─ python 3.12.* , which conflicts with any installable versions previously reported.

解决方法 #

方法1：使用pip安装evaluate #

Hugging Face官方库的pip源更新速度通常快于conda默认源，Python 3.12可直接通过pip安装兼容版本：

• 激活目标conda环境：

  conda activate your_env_name
  

• 执行pip安装：

  pip install evaluate
  

方法2：创建兼容Python版本的新conda环境 #

如果需要继续用conda管理依赖，可创建指定Python版本（如3.11，evaluate 0.4.0支持该版本）的新环境：

• 创建新环境：

  conda create -n hf_llm_env python=3.11
  

• 激活环境：

  conda activate hf_llm_env
  

• 安装evaluate：

  conda install evaluate
  

方法3：通过conda-forge源安装 #

conda-forge社区源的包更新更及时，可能已支持Python 3.12的evaluate版本：

• 添加conda-forge源并设置优先级：

  conda config --add channels conda-forge
  conda config --set channel_priority strict
  

• 安装evaluate：

  conda install evaluate
