使用taos.connect()，提示UserWarning: pandas only support SQLAlchemy connectable(engine/connection) ordatabase string URI or sqlite3 DBAPI2 connectionother DBAPI2 objects are not tested, please consider using SQLAlchemy。似乎也没有正常运行

同样是主线程可以正常调用，在子线程里会一直卡在connect的地方

明白，我测试使用create_engine 和 taso.connect在windows下都是好的，但是在ubuntu 20上无法正常工作

测试使用您的这段是可以的，区别在于使用的是threading和multiprocessing，我认真看一下这二者有什么区别

是的，每个传感器采样频率不一样

and how can I use akka in cdh?somebody said must shade the akka when use sbt?I'm not very clear about that.

Thanks!

I checked the source code, May be the question is at the 2232 line in file `netCDF4/_netCDF4.pyx`: https://github.com/Unidata/netcdf4-python/blob/master/netCDF4/_netCDF4.pyx#L2232 ``` ierr = nc_open(path, NC_NOWRITE, &grpid) ``` But I don't know what's...

@jswhit Yes, and it can be opened in shell mode

And I use `ubyte.nc` which is your test file,It works well.
