"blocksparse_conv_op" How does the function work?

[yiwusuorao]

I think code " y = bs_conv(k, x)" call the function in "conv.py" line 507
def call(self, F, I):
assert I.get_shape()[1] == self.C
output = blocksparse_conv_op(
self.fprop_grid, self.bprop_grid, self.updat_grid,
self.mpq_lut, self.dhw_lut, self.ck_lut,
F, I, c_type=I.dtype,
mode=0, overlapC=self.overlapC, overlapK=self.overlapK,
C=self.C, K=self.K, DHW=self.DHW, MPQ=self.MPQ, trs=self.trs,
magic_trs=self.magic_trs[0], shift_trs=self.magic_trs[1],
dimF=F.get_shape().as_list(), fshare=self.fshared, bshare=self.bshared, debug=self.debug
)
return output

but where is the function "blocksparse_conv_op"?How does the function work?
Thanks in advance
