jittor.nn.Conv2d的stride接受非法参数异常

[PhyllisJi]

关键错误信息

jittor.nn. Conv2d的stride设置为-1(或者其他非法值)时，模型定义时不会对此抛出异常，在执行模型逻辑时，计算oh、ow时得到负数，从而执行assert oh>0 and ow>0抛出异常。

预期行为

jittor.nn. Conv2d的stride非法时，应该拒绝该参数，并抛出正确的异常信息提醒用户，以防止底层算子出现未知问题，并不影响其他正常运算。

最小复现

conv = nn.Conv2d(3, 5, 2, stride=-1)
input1 = jt.randn(4, 3, 10, 10)
output = conv(input1)
print(output.shape)
