我想在我的 anaconda中安装kraken 。所以我按照从PyPI得到的这个命令-

pip install kraken

但我最终遇到了一个错误，那就是 -

Collecting kraken

Collecting python-bidi

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

我也尝试过anaconda的指令-

conda install -c bioconda kraken

但这一次我得到了——

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

To search for alternate channels that may provide the conda package you're
looking for, navigate to

我已经知道的所有这些命令都在Anaconda Prompt 中。因此，请帮助我了解如何安装 kraken。TIA。

GitHub 存储库有通过 Conda 安装的说明。它显示了创建一个新的环境，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，该--name标志可用于指定除默认 ( kraken) 以外的环境名称。

在现有环境中安装

Technically, one can also use a YAML to install into an existing env. However, since it involves a pip-based installation, it is not recommended to install this to the base env (see Using Pip in a Conda Environment).

conda env update -n my_env -f environment.yml
