我用deap2.1做分析，老是出现一个为0的输出文件，或是出现“bad input tableau in simplx,Press Enter to Continue”，请教高手这个什么原因造成的？我的数据里有0.
shujv4（baoliu2）.txt       DATA FILE NAME
shujv4（baoliu2）out.txt       OUTPUT FILE NAME
11               NUMBER OF FIRMS
1                 NUMBER OF TIME PERIODS
3                NUMBER OF OUTPUTS
3                NUMBER OF INPUTS
1                0=INPUT AND 1=OUTPUT ORIENTATED
1                 0=CRS AND 1=VRS
0                 0=DEA(MULTI-STAGE), 1=COST-DEA, 2=MALMQUIST-DEA, 3=DEA(1-STAGE), 4=DEA(2-STAGE)


红色部分的1换成0时可以出结果，只是会出现以下红色字体，不知道是怎么回事？求教了。
