Hello! Welcome to our forums and Thank you for your question!

Could you kindly check if the same is being logged during the run?

Logged values get appended to `run.history()`

I dont know how to get full log from web interface. (In log tab i cant download, its redirect to storage. googleapis. com and it is empty )  
Downloaded one of metrics with 72 rows  
And `run.history()` return **different** results 52 and 46

```python
 df=run.history()
filtered_df = df[df['test/epoch'].notnull()]
filtered_df.to_csv('/home/dereyly/tmp/hist2.csv')

Hi @dereyly , if you’d like to chart a link to your project page ([wandb.ai/](http://wandb.ai/)/\<project\_name\>) I can take a look and see what exactly is going on.
