cplex - 将 CPLEX Studio 升级到学术版

问题描述

我已经从https://www-03.ibm.com/isc/esd/dswdown/searchPartNumberResults.wss下载了 CPLEX Studio 20.1 ，并将它与 Python 一起使用。

不幸的是，在运行 Python 代码时，出现错误：

   CPLEX Error  1016: Community Edition. Problem size limits exceeded.

即使我有学术帐户。

我的问题是：如何将我的 CPLEX 工作室升级到学术版？

如果我跑

python -m docplex.mp.check_list

在主终端我得到：

* system is: Darwin 64bit
* Python version 3.8.8, located at: /opt/anaconda3/bin/python
* docplex is present, version is 2.18.200
* CPLEX library is present, version is 20.1.0.0, located at: /opt/anaconda3/lib/python3.8/site-packages
* pandas is present, version is 1.2.4
* Your cplex version 20.1.0.0 is the latest available
> No problem found: you're all set!

但是，如果我在 PyCharm (conda) 的终端中运行相同的命令，我会得到：

* system is: Darwin 64bit
* Python version 3.8.10, located at: /Users/*username*/.conda/envs/bin/python
* docplex is present, version is 2.21.207
* CPLEX library is present, version is 20.1.0.0, located at: /Users/*username*/.conda/envs/lib/python3.8/site-packages
* pandas is present, version is 1.3.2
* Your cplex version 20.1.0.0 is the latest available
! Cplex promotional version, limited to 1000 variables, 1000 constraints

* diagnostics: 1
  -- Your local CPLEX edition is limited. Consider purchasing a full license.

解决方案

要确定 DOcplex 使用哪个 CPLEX 运行时，请check_list在命令行运行模块（在 Python 路径中使用 docplex）：

python -m docplex.mp.check_list
