我遇到了np.linalg.lstsq()“大”数组导致可怕（非pythonic）崩溃的错误。
一些例子：
这有效：
python -c "import numpy as np; np.linalg.lstsq(np.random.randn(10000,25),np.random.randn(10000))"
这失败了，有相当大的回溯：
python -c "import numpy as np; np.linalg.lstsq(np.random.randn(10000,26),np.random.randn(10000))"
26 处的失败和 25 处的成功是可重复的，并且显然可以重复到python -c "import numpy as np; np.linalg.lstsq(np.random.randn(26,26),np.random.randn(26))"，低于25python -c "import numpy as np; np.linalg.lstsq(np.random.randn(25,26),np.random.randn(25))"和较小的所有工作。
谁能帮我解释错误信息或找出问题所在？
（numpy 版本是 1.7.1）
