get memory usage Why Variety big of result question



Question
Why does the result of memory_get_usage() change so much?
Solution
There is a set of programs. I use memory_Get_usage in the footer to output the memory usage. The results vary greatly. Sometimes it is more than 700k, sometimes it is more than 1m, sometimes it is 5M. After restarting apache, everything is normal again

The output page is the same page, and no new data has been added to the database, so I don't understand it.


Netizens’ suggestions:
Since it is memory usage, there is no constant. . . Look at your task manager, which memory remains unchanged?
Netizens’ suggestions:
But how many times the amount of change
Netizens’ suggestions:

Is it always increasing or changing irregularly
Netizens’ suggestions:
As time accumulates, it becomes larger, but it takes a relatively long time, such as a few hours to change.

How to fine-tune deepseek locally How to fine-tune deepseek locally Feb 19, 2025 pm 05:21 PM

Local fine-tuning of DeepSeek class models faces the challenge of insufficient computing resources and expertise. To address these challenges, the following strategies can be adopted: Model quantization: convert model parameters into low-precision integers, reducing memory footprint. Use smaller models: Select a pretrained model with smaller parameters for easier local fine-tuning. Data selection and preprocessing: Select high-quality data and perform appropriate preprocessing to avoid poor data quality affecting model effectiveness. Batch training: For large data sets, load data in batches for training to avoid memory overflow. Acceleration with GPU: Use independent graphics cards to accelerate the training process and shorten the training time.
