vnpy版本1.9.2
回测的时候把tb下的csv文件导入mongo一直显示No such file or directory: 'rb888_15min.csv。
文件名是没问题的，用loadCsv试了，也是一样的错。
请问要怎么处理？

代码：
from vnpy.trader.app.ctaStrategy.ctaHistoryData import loadTbCsv
if name == 'main':
loadMcCsv('rb888_15min.csv', 'VnTrader_15Min_DB', 'rb888')

报错：
IOError Traceback (most recent call last)

121 for d in reader:

IOError: [Errno 2] No such file or directory: 'rb888_15min.csv'

请在csv所在的目录下来启动加载程序

在csv所在目录下启动还是不可以

运行loadCsv.py
也会报错。

CSV文件的表头格式，和loadMcCsv函数中的不一致导致的
