6 days ago 你可以提供完整的代码吗 @Met4physics 可以的，我是想要将wenet开源工具包中transformer的变体conformer用snn予以实现，目前才刚刚导入了spikingjelly框架，但是发现就不能进行训练了，如果注释导入的代码，则可以正常训练。 以下是我的encoder代码。

fashion
Here we should pay special attention to computation cache in the
streaming style forward chunk by chunk. Three things should be taken
into account for computation in the current network:
1. transformer/conformer encoder layers output cache
2. convolution in conformer
3. convolution in subsampling
However, we don't implement subsampling cache for:
1. We can control subsampling module to output the right result by
overlapping input instead of cache left context, even though it
wastes some computation, but subsampling only takes a very
small fraction of computation in the whole model.
2. Typically, there are several covolution layers with subsampling
in subsampling module, it is tricky and complicated to do cache
with different convolution layers with different subsampling
rate.
3. Currently, nn.Sequential is used to stack all the convolution
layers in subsampling, we need to rewrite it to make it work
with cache, which is not prefered.

目前问题原因并不明确，neuron源代码中没有使用tensorboardx，暂时的解决方法我觉得你可以试试wandb或者手动打印来取代tensorboardx
Description
我在尝试使用惊蛰框架，将ann网络结构转换为snn网络结构时，导入惊蛰框架后，原本可以正常进行的ANN训练代码出现警告，且后续的训练流程无法进行了。 警告内容为：
导入的代码为：
而我并没有使用导入的惊蛰模块，仅仅是导入了惊蛰框架。
请问为什么会发生这种情况？
