3. Basic Usage

3.1 Start DeepSeek

deepseek

3.2 Data Import

Import data from various sources:

CSV

deepseek import --format csv --file data.csv

JSON

deepseek import --format json --file data.json

Database (SQL)

deepseek import --format sql --db mydatabase --table mytable

3.3 Data Query

Use SQL syntax to query data:

Simple query

deepseek query "SELECT * FROM mytable"

Conditional query

deepseek query "SELECT * FROM mytable WHERE age > 30"

Aggregation

deepseek query "SELECT department, AVG(salary) FROM mytable GROUP BY department"

4. Advanced Features

4.1 Data Cleaning

Deduplication

deepseek clean --deduplicate

Fill missing values

deepseek clean --fillna 0

Type conversion

deepseek clean --convert --column age --type int

4.2 Data Analysis

Descriptive statistics

deepseek analyze --describe

Regression analysis

deepseek analyze --regression --x age --y salary

Clustering

deepseek analyze --cluster --columns age,salary --k 3

4.3 Data Visualization

Bar chart

deepseek visualize --type bar --x category --y value

Line chart

deepseek visualize --type line --x date --y value

Export chart

deepseek visualize --export chart.png

5. Usage Tips

5.1 Batch processing

Process multiple files with a script, e.g., batch import CSV files:

for file in *.csv; do
  deepseek import --format csv --file $file
done

5.2 Scheduled tasks

Use cron on Linux to run imports automatically:

crontab -e

0 1 * * * deepseek import --format csv --file /path/to/data.csv

5.3 Plugin extensions

Install additional plugins, such as a machine‑learning extension:

deepseek plugin install deepseek-ml

After installation, you can train and predict models:

deepseek ml --train --model linear_regression --x age --y salary

6. Common Issues and Solutions

6.1 Import failure

Problem: File format error during import.

Solution: Verify the file format, path, and permissions.

6.2 Slow query performance

Problem: Queries on large datasets are slow.

Solution: Optimize SQL, use indexes, and increase memory.

6.3 Incorrect chart rendering

Problem: Generated charts display incorrectly.

Solution: Check data formats, ensure consistent types, and adjust chart parameters.

7. Conclusion

DeepSeek is a powerful, flexible tool for data processing, suitable for a wide range of scenarios. By mastering its basic functions and advanced techniques, you can efficiently perform data import, cleaning, analysis, and visualization, greatly improving productivity.
