这个错误提示中显示,程序无法找到指定的文件 "D:\\A过铁精矿\\ related.txt"。很可能是文件名或路径有误。请检查一下文件名和路径是否正确,或者尝试使用绝对路径来确保程序能够正确地找到文件。此外,你使用了 skipfooter 参数,但是在使用 'c' 引擎的情况下,它不被支持,因此建议使用 'python' 引擎或者不使用 skipfooter 参数。
你可以尝试使用以下代码:
```
import pandas as pd
file_path = 'D:\\A过铁精矿\\ related.txt'
df = pd.read_csv(file_path, header=None, skiprows=1, delimiter='\t', engine='python')
```
希望这能帮到你。

ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support skipfooter; you can avoid this warning by specifying engine='python'.
这个警告是因为使用了skipfooter参数,而pandas默认使用的C engine不支持skipfooter参数。为了避免这个警告,可以将read_csv函数的engine参数设置为python,这样就可以使用Python engine来解析文件,而不会出现警告。
以下是一个修改后的示例代码:
```python
import pandas as pd
import json
# 读取.OUT文件
df = pd.read_csv('example.out', sep=',', skiprows=8, engine='python', skipfooter=2)
# 提取节点和管道的流量信息
node_flows = df.loc[df['Element_type'] == 'Node', ['Element_name', 'Flow_rate']]
pipe_flows = df.loc[df['Element_type'] == 'Link', ['Element_name', 'Flow_rate']]
# 构造字典对象
data = {
'node_flows': node_flows.to_dict('records'),
'pipe_flows': pipe_flows.to_dict('records')
}
# 将字典转换成JSON格式的字符串
json_data = json.dumps(data)
# 返回JSON格式的字符串
return json_data
```
这样就可以避免警告了。
c.e.s.SpringBootprojectApplicationTests : No active profile set, falling back to 1 default profile: "default"
这条提示"c.e.s.SpringBootprojectApplicationTests : No active profile set, falling back to 1 default profile: 'default'"意味着在Spring Boot项目的测试中没有激活任何配置文件,因此默认使用了"default"配置文件。在Spring Boot中,可以通过激活不同的配置文件来适应不同的环境需求。如果在测试中没有明确指定使用哪个配置文件,Spring Boot会自动使用"default"配置文件作为默认值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
