求助：执行import lava.lib.dl.slayer失败，疑似lava.lib.dl.slayer缺失

[zzaa888]

您好，我在pip完毕spikingjelly后，import任何activation_based里面的包总会显示报错定位至lava_exchange.py文件中的import lava.lib.dl.slayer语句。

报错显示为：
AttributeError Traceback (most recent call last)
in
----> 1 from spikingjelly.activation_based import neuron, encoding, functional, surrogate, layer
~\Desktop\spikingjelly-master\spikingjelly-master\spikingjelly\activation_based\neuron.py in
3 import torch
4 import torch.nn as nn
----> 5 from . import surrogate, base, lava_exchange
6 from .. import configure
7 import math
~\Desktop\spikingjelly-master\spikingjelly-master\spikingjelly\activation_based\lava_exchange.py in
11 slayer = None
12
---> 13 class FasterLavaDense(slayer.synapse.Dense):
14 @staticmethod
15 def convert_from(slayer_dense: slayer.synapse.Dense):

AttributeError: 'NoneType' object has no attribute 'synapse'

我查阅lava_exchange.py后发现疑似在执行import lava.lib.dl.slayer as slayer语句时失败，导致cannot find reference ‘synapse’ in ' None'
请问这种情况该如何解决呢？感激不尽！

是从源代码安装的？用git pull更新代码后再试试

重置了环境后，又重新clone了一遍恢复正常，谢谢您的答复！
