在graphlab中，我面临以下问题：
feat1 = gl.SFrame.read_csv(dir_path + '/data/' + 'file_1.csv')
“feat1”包含一个名为“movieId”的列，类型为“int”。

另一方面，存在一个标头名称为“movieId”并键入“str”的 SFrame
movieIds.dtype
<bound method SFrame.dtype of Columns:
movieId str
Rows: 13140
Data:
+---------+
| movieId |

| 1 |
| 2 |
| 3 |
| 4 |
| 5 |
| 6 |
| 7 |
| 8 |

| 10 |
+---------+
[13140 rows x 1 columns]
Note: Only the head of the SFrame is printed.
You can use print_rows(num_rows=m, num_columns=n) to print more rows and columns.>
尝试加入他们时，我收到此错误：
feat1 = movieIds.join(feat1, on='movieId', how='inner')
RuntimeError: Runtime Exception. Columns movieId and movieId do not have the same type in both SFrames.
如何控制导入的“csv”的一列以特定数据类型导入？在您看来，克服这个问题的最佳方法是什么？非常感谢您的意见。
