Pulp.pulpTestAll（）測試失敗，需要解壓的值太多

我的操作系統是窗口7，紙漿版本是1.6.1，gurobi版本是7.0.1。 gurobipy可以成功導入。 pulp.solvers.GUROBI確實通過了測試，所以我可以使用gurobi。但是，pulp.solvers.CPLEX_CMD失敗。這裏是錯誤信息：Pulp.pulpTestAll（）測試失敗，需要解壓的值太多

你知道了嗎？我收到了同樣的錯誤。 – SashaZd

@SashaZd，不，我只是忽略了錯誤 –

我卸載並重新安裝了gurobi。這次它工作:) – SashaZd

我得到了同樣的錯誤。這與Gurobi_CMD有關。古羅比通過了所有的測試，但在Gurobi_CMD上失敗了。

我解決了它通過卸載並重新安裝Gurobi，並更改PuLP的.cfg文件，以正確指向Gurobi安裝。
