无法安装 kraken（图像优化器）

Question

我想在我的蟒蛇中安装 kraken。所以我按照从 PyPI -

得到的命令

pip install kraken

但我最终遇到了一个错误，那就是 -

Collecting kraken
Using cached kraken-2.0.8-py3-none-any.whl (643 kB)
Collecting python-bidi
  Downloading python_bidi-0.4.2-py2.py3-none-any.whl (30 kB)

ERROR: No matching distribution found for torch>=1.0.0 (from kraken)

我也试过 anaconda -

的指令

conda install -c bioconda kraken

但是这次我有 -

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

我遇到的所有这些命令都在 Anaconda Prompt 中。 所以请帮助我了解如何安装 kraken。 TIA.

Answer 1

The GitHub repository 有通过 Conda 安装的说明。它显示了创建一个新环境，这通常是一种很好的做法。

非CUDA版本

$ wget https://raw.githubusercontent.com/mittagessen/kraken/master/environment.yml
$ conda env create -f environment.yml

CUDA 版本

$ wget https://raw.githubusercontent.com/mittagessen/kraken/master/environment_cuda.yml
$ conda env create -f environment_cuda.yml

请注意，--name 标志可用于指定不同于默认名称 (kraken) 的环境名称。

在现有环境中安装

从技术上讲，也可以使用 YAML 安装到现有环境中。但是，由于它涉及基于 pip 的安装，因此不建议将其安装到 base env（参见 Using Pip in a Conda Environment）。

conda env update -n my_env -f environment.yml
