Error using lassoglm>glmProcessData

The error said:

[After stripping NaNs and Infs, either 'X' has too few rows or 'Weights' has too few positive values.

Error in lassoglm (line 328)

glmProcessData(x, y, distr, 'off', offset, pwts); ]

The error code in lassoglm:

[X, Y, offset, pwts, dataClass, nTrials, binomialTwoColumn] = ...

glmProcessData(x, y, distr, 'off', offset, pwts);

I checked that size of input x is normal size. Even all weights equal to 0, I eed these output.

How to sovle this problem?

If you are passing in Weights, at least one weight must be positive.

Otherwise: you need at least one row of X to contain finite values. You probably have missing data in X (or possibly X is empty)
