2、get sug pc failed:ral to rec_sug_pc failed:max retries=1, err: code=1004, msg=connect failed, with raw error: fallback: dial tcp 10.229.163.19:8053: connect: connection refused

The error message indicates that the system is unable to connect to the remote server for the specified purpose. Here's a breakdown of the error message:

"get sug pc failed:ral to rec_sug_pc failed:max retries=1, err: code=1004, msg=connect failed, with raw error: fallback: dial tcp 10.229.163.19:8053: connect: connection refused"

get sug pc failed: This suggests that the system is attempting to get a suggestion from a "suggestion PC" ("sug pc"), but the attempt has failed.

ral to rec_sug_pc failed: This part indicates that the system is trying to reach the "rec_sug_pc" ("recommendation suggestion PC") but has failed.

max retries=1: This means that the system has attempted to connect to the remote server once, but has not been successful.

err: code=1004, msg=connect failed: The error code 1004 indicates a "connection refused" error. This means that the remote server is not responding to connection attempts.

with raw error: fallback: dial tcp 10.229.163.19:8053: connect: connection refused: This part provides more details about the connection failure. It specifies that the system is attempting to connect to a TCP port (8053) on the IP address 10.229.163.19, but the connection request is being refused.

Possible Causes:

Network issue: Check if there is any network connectivity issue between the system and the remote server.

Firewall or security configuration: Ensure that the firewall or security configuration on the remote server allows incoming connections on port 8053.

Remote server status: Check if the remote server is running and listening on port 8053.

Incorrect IP address or port: Verify that the IP address and port specified in the connection attempt are correct.

Troubleshooting Steps:

1. Check the network connectivity between the system and the remote server.

2. Review the firewall or security configuration on the remote server to ensure that port 8053 is open for incoming connections.

3. Check the status of the remote server and ensure that it is running and listening on port 8053.

4. Confirm that the IP address and port specified in the connection attempt are correct.

3、code

import numpy as np

import pandas as pd

import matplotlib.pyplot as plt

Load the data

df = pd.read_csv('data.csv')

Create a scatter plot of the data

plt.scatter(df['x'], df['y'])

plt.xlabel('x')

plt.ylabel('y')

plt.title('Scatter Plot of Data')

Show the plot

plt.show()
