Python没有完成以下函数(使用iPython笔记本和Graphlab)
def print_submission_file(var, filename='submission.txt'):
with open(filename, 'w') as f:
f.write('Id,Sales\n')
for row in var:
f.write(str(row['Id']) + ',' + str(row['Prediction']) + '\n')
print_submission_file(test, 'submission.txt')
这是脚本停止时的日志(5/10分钟后)

所以函数在提交.txt但从来没有完成for循环。。。 谢谢你的帮助。我真的不知道该怎么办。你知道吗
您的循环可能需要很长时间才能以这种方式遍历SFrame。错误消息是因为您用Ctrl-C取消了命令(我猜是这样)。你知道吗
如果您只想用这两列编写csv,请尝试以下操作(假设var是SFrame):
