Python 无法使用PIP升级Scipy

我尝试在Ubuntu 16.04上使用PIP升级Scipy，但总是收到这个错误。我不知道发生了什么事。进度达到99%，然后停止，并抛出此错误

我已尝试升级pip，但仍然出现相同的错误

MemoryError

尝试在安装期间使用禁用缓存

pip install --no-cache-dir packageName

其中packageName是

scipy

在本例中

最后一行是“MemoryError” 您正在使用虚拟环境吗

如果是这样，则环境可能需要为其分配更多内存

转到播放器>管理>虚拟机设置

在这里，拖动滑块以选择要分配的更高内存值

重新启动虚拟环境以进行更改

我希望这有帮助

非常感谢，工作得很好！我会接受答案，一旦它让我：）
