5. Usage Tips
1. Batch Processing
If you need to process multiple files, you can use scripts for batch processing. For example, batch importing CSV files:
for file in *.csv; do
deepseek import --format csv --file $file
done
2. Scheduled Tasks
By setting up scheduled tasks, you can regularly execute data import and analysis. For example, using <span>cron</span> to set up scheduled tasks in Linux:
1. Open the crontab editor:
crontab -e
2. Add the following task to execute data import at 1 AM every day:
0 1 * * * deepseek import --format csv --file /path/to/data.csv
3. Plugin Extensions
DeepSeek supports extending functions through plugins. For example, install the machine learning plugin:
deepseek plugin install deepseek-ml
After installation, you can use the functions provided by the plugin, such as model training and prediction:
deepseek ml --train --model linear_regression --x age --y salary
6. Common Issues and Solutions
1. Import Failure
-
Problem: An error message appears indicating file format error during data import.
-
Solution: Check if the file format is correct and ensure the file path and permissions are correct.
2. Slow Query Speed
-
Problem: The speed is slow when querying large datasets.
-
Solution: Optimize the query statement, use indexing, and increase system memory.
3. Chart Display Anomalies
-
Problem: The generated charts do not display correctly.
-
Solution: Check the data format, ensure data types are consistent, and adjust chart parameters.
