Couldn't obtain all predicted values when using trained models

[XuanrZhang]

Hi @kellycochran,

When I follow the 0_generate_predictions_for_other_notebooks.ipynb script to get predicted values by using trained models.

I couldn't receive all predicted values, only multiples of the batch_size. Are there any changes I can make to obtain all predicted values?

For example, I got 7009 sequences in total, I just got 7000 predicted values as output(with batch_size 1000). how can I store the last 9 values together?

Thanks in advance.

Best,
Xuan

Hi Xuan,

One way to do this would be to set the batch_size to 1, but at the cost of efficiency. You could also modify the code inside ValGenerator so that it loads the full dataset, including any partial batches:

1. Modify the line self.steps = lines_in_file // batchsize inside get_steps(..)to be self.steps = math.ceil(lines_in_file / batch_size), and import math elsewhere
2. Modify the expression (batch_index + 1) * self.batchsize inside __getitem__(..) to instead be min(len(self.coords), (batch_index + 1) * self.batchsize). This way, there will not be an error if the final batch is size < batch_size.

Hope that helps!

Hi @kellycochran,

Thanks a lot for your reply! I will try to modify ValGenerator.

One more question here, if I set the batch_size as 1 to make a prediction, does that change predicted values?

A batch_size of 1 will not change the predicted values.
