大数据集的数据重塑

Question

我想重塑我的np数组并将其呈现为DF。我的初始数据集是2930行。我的标题/列包含以下（80）元素：

Order;PID;MS SubClass;MS Zoning;Lot Frontage;Lot Area;Street;Alley;Lot Shape;Land Contour;Utilities;Lot Config;Land Slope;Neighborhood;Condition 1;Condition 2;Bldg Type;House Style;Overall Qual;Overall Cond;Year Built;Year Remod/Add;Roof Style;Roof Matl;Exterior 1st;Exterior 2nd;Mas Vnr Type;Mas Vnr Area;Exter Qual;Exter Cond;Foundation;Bsmt Qual;Bsmt Cond;Bsmt Exposure;BsmtFin Type 1;BsmtFin SF 1;BsmtFin Type 2;BsmtFin SF 2;Bsmt Unf SF;Total Bsmt SF;Heating;Heating QC;Central Air;Electrical;1st Flr SF;2nd Flr SF;Low Qual Fin SF;Gr Liv Area;Bsmt Full Bath;Bsmt Half Bath;Full Bath;Half Bath;Bedroom AbvGr;Kitchen AbvGr;Kitchen Qual;TotRms AbvGrd;Functional;Fireplaces;Fireplace Qu;Garage Type;Garage Yr Blt;Garage Finish;Garage Cars;Garage Area;Garage Qual;Garage Cond;Paved Drive;Wood Deck SF;Open Porch SF;Enclosed Porch;3Ssn Porch;Screen Porch;Pool Area;Pool QC;Fence;Misc Feature;Misc Val;Mo Sold;Yr Sold;Sale Type;Sale Condition;SalePrice

我尝试了以下代码：

df = pd.DataFrame(np.array(results[1:]).reshape(2930,15,-1), columns = results[0])

结果==＆gt;

  

ValueError：无法将大小为2930的数组重塑为形状   （2930,15，newaxis）

为什么这不可能？将get数据集导入DataFrame的可能解决方案？谢谢，非常感谢。

如果您最初是从文件中读取它，可以使用pd.read_csv（sep =＆＃39 ;;＆＃39;）来解析每个列...
