这个错误的信息显示在代码中的`assert_process_still_running`函数中,它在尝试访问`Service`对象的`process`属性时引发了一个属性错误。这可能是因为`Service`对象没有被正确地初始化,或者在初始化时没有正确地设置`process`属性。
要解决这个问题,你需要检查`Service`对象的初始化,确保它在初始化时设置了`process`属性,并且在访问`process`属性之前确保`Service`对象已正确初始化。你还可以检查`Service`对象的定义,确保它包含`process`属性的定义。

这个错误是由于SRE模块版本不匹配导致的。SRE模块是Python中的正则表达式引擎模块,用于处理正则表达式的编译和匹配。
解决这个问题的方法是重新安装Python环境或更新相关的依赖库。可以尝试以下步骤:
1. 确保你的Python版本是最新的,可以使用命令`python --version`来查看版本信息。
2. 如果你使用的是Anaconda环境,可以尝试更新Anaconda,使用命令`conda update anaconda`来更新。
3. 更新pip工具,使用命令`pip install --upgrade pip`来更新。
4. 尝试重新安装相关的依赖库,可以使用命令`pip install -r requirements.txt`来重新安装项目所需的依赖。

根据错误信息,可以看到程序出现了一个 AssertionError 异常,提示 "b must be a positive integer"。这个错误是由 gamma_func 函数中的 assert 语句触发的,说明输入参数 b 不满足要求。
根据代码,我们知道 gamma_func 函数要求输入参数 b 是正整数。因此,建议检查调用 gamma_func 函数时所传入的参数是否满足要求。如果不满足要求,可以进行相应的调整,确保输入参数 b 是正整数。
另外,如果需要捕获 AssertionError 异常并进行相应的处理,可以使用 try-except 语句来实现。例如:
```python
try:
gamma_params, _ = curve_fit(gamma_func, new_bin_centers, new_hist, p0=p2)
except AssertionError as e:
print("Error: ", e)
```
这里使用 try-except 语句捕获 AssertionError 异常,并输出相应的错误信息。
