Preprocessing error: self.ctx_write_uniform, moderngl.error: invalid uniform size

I met error when executing preprocessing_data.py

Applying threed_front_bedroom filtering

I have already tried to the following solution, but they cannot solve my problem.

'''
self._Ns = float([
float(l.strip().split()[1:][0])
for l in lines if l.strip().startswith("Ns")
][0])
'''
self._Ns = 400

Please anyone help me.
