用numpy将csv加载到2D矩阵中以进行绘图。

给定这个CSV文件：

"A","B","C","D","E","F","timestamp"
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291111964948E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291113113366E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291120650486E12

我只想将其加载为一个3行7列的矩阵/数组。然而，由于某种原因，我只能得到一个有3行（每行一个）且没有列的ndarray。

r = np.genfromtxt(fname,delimiter=',',dtype=None, names=True)
print r
print r.shape
[ (611.88243, 9089.5601000000006, 5133.0, 864.07514000000003, 1715.3747599999999, 765.22776999999996, 1291111964948.0)
 (611.88243, 9089.5601000000006, 5133.0, 864.07514000000003, 1715.3747599999999, 765.22776999999996, 1291113113366.0)
 (611.88243, 9089.5601000000006, 5133.0, 864.07514000000003, 1715.3747599999999, 765.22776999999996, 1291120650486.0)]
(3,)

我可以手动迭代并将其调整为我想要的形状，但这似乎很愚蠢。我只想将其加载为一个正确的矩阵，这样我就可以在不同的维度上切片并绘制它，就像在matlab中一样。
