由于某些原因,我需要将其导入另一个 tf 状态文件。所以我运行了这个命令:
terraform import module.rds.aws_cloudwatch_log_subscription_filter.rds_logs_delivery["prod-service-reports.audit"] rds-logs-delivery-prod-service-master

我该如何解决?我试过了 …
我发现使用以下方法很容易计算活动连接数
redis_sip = redis.Redis(host="localhost", port=6379, db=0)
redis_sip.setbit(skey, 1, 1)
redis_sip.setbit(skey, 2, 1)
redis_sip.setbit(skey, 3, 0)
redis_sip.setbit(skey, 4, 1)
print(redis_sip.bitcount(skey)) # shows me 3 connections
Run Code Online (Sandbox Code Playgroud)
但为了实现这一点,我需要能够为每个单独的位设置一个 TTL。
即当远程代理建立连接时,我可以将该位设置为 1。如果支持按位到期,则在一段不活动时间后该位将被翻转。
这在Redis中可行吗?如果不是,有什么替代方案?
我有一个非常大的形状张量(512,3,224,224)。我将其以 32 个批次输入到模型中,然后保存与目标标签相对应的分数2。在每次迭代中,在每个切片之后,形状都会发生scores变化。这会导致以下错误。我做错了什么以及如何解决它。

我希望输出为[1,2],但它会打印[].
这与我的期望相反.
我在代码中犯了什么错误吗?如果没有,我认为它是这样工作的,因为当创建属性test1时,它被绑定到基类A的f1函数.有什么可能的替代实现来实现我想要的?
