ERROR: Cannot install gluonts, mxnet, numpy and pandas because these package versions have conflicting dependencies

Question

我想安装某些软件包：

pip install gluonts==0.8.0 mxnet~=1.7 pathlib==1.0.1 numpy==1.17.2 pandas==1.0.5 ujson==4.0.2 torch~=1.6 pytorch-lightning~=1.1

但是在安装过程中，出现了以下错误：

ERROR: Cannot install gluonts==0.8.0, mxnet==1.7.0.post1, mxnet==1.7.0.post2, numpy==1.17.2 and pandas==1.0.5 because these package versions have conflicting dependencies.

The conflict is caused by:
The user requested numpy==1.17.2
gluonts 0.8.0 depends on numpy~=1.16
pandas 1.0.5 depends on numpy>=1.13.3
mxnet 1.7.0.post2 depends on numpy<1.17.0 and >=1.8.2
The user requested numpy==1.17.2
gluonts 0.8.0 depends on numpy~=1.16
pandas 1.0.5 depends on numpy>=1.13.3
mxnet 1.7.0.post1 depends on numpy<1.17.0 and >=1.8.2

我指的是这些安装的以下站点： https://business-science.github.io/modeltime.gluonts/articles/managing-envs.html

有没有办法在没有任何依赖冲突的情况下安装所有这些包（即使它必须在新的 python 环境中，例如 pipenv myenv）？

Answer 1

您必须安装 numpy 1.16.6 才能与 mxnet 1.7 兼容。由于 python 大于 3.7 的 numpy 1.16.6 没有二进制 (whl) 文件，因此您需要一个编译器从源代码（一个 zip 文件）构建 numpy。另见 how to solve numpy error while installing mxnet?

或者使用 python 3.7 代替 numpy 1.16.6 和 mxnet 1.7
