`np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
Chapter 7, Token classification has a .compute_metric() function that uses argmax() instead of softmax(). I have attached it below. I’m wondering why does this not cause problems with gradient back-propagation? Argmax is non-differentiable, so I would assume there’d be problems, but example clearly works, and I must be missing something here.
link:
code:
import numpy as np
def compute_metrics(eval_preds):
logits, labels = eval_preds
predictions = np.argmax(logits, axis=-1)
# Remove ignored index (special tokens) and convert to labels
true_labels = [[label_names[l] for l in label if l != -100] for label in labels]
true_predictions = [
[label_names[p] for (p, l) in zip(prediction, label) if l != -100]
for prediction, label in zip(predictions, labels)
]
all_metrics = metric.compute(predictions=true_predictions, references=true_labels)
return {
"precision": all_metrics["overall_precision"],
"recall": all_metrics["overall_recall"],
"f1": all_metrics["overall_f1"],
"accuracy": all_metrics["overall_accuracy"],
}
I’ve found several issues with the “Training a causal language model from scratch” tutorial, you can find those below:
- In the “Training with
Accelerate” section, the variable ‘tokenized_dataset’ should be corrected to ‘tokenized_datasets’. This appears to be a typo. - There is a deprecation issue to note: Replace
Accelerator(fp16=True)withAccelerator(mixed_precision='fp16')to use the updated syntax. - Regarding the evaluation with the accelerator, the correct code should be
losses.append(accelerator.gather(outputs.loss.view(-1)))sinceoutputs.lossreturns a scalar and does not have a shape. - In the accelerator training loop, the variable ‘samples_per_step’ is undefined. I assume it should be the same as ‘batch_size’, which was 32.
i hope this helps, best.
This seems like a typo to me, In the QuestionAnswering section, inside the fuction preprocess_training_examples(examples) there is a loop that finds the end position of the answer, the following code is in the course page.
# Find the start and end of the context
idx = 0
while sequence_ids[idx] != 1:
idx += 1
context_start = idx
while sequence_ids[idx] == 1:
idx += 1
context_end = idx - 1
This gives an index out-of-range error. I think the correct version is
while sequence_ids[idx] != 1:
idx += 1
context_end = idx - 1
When training a causal language model from scratch , i am getting this error:

You could try to create a new model under your account.
I got confusion about some code snippet of " Fine-tuning a masked language model" part. Why do we need to repeat “loss” in below code ?
for step, batch in enumerate(eval_dataloader):
with torch.no_grad():
outputs = model(**batch)
loss = outputs.loss
losses.append(accelerator.gather(loss.repeat(batch_size)))
losses = torch.cat(losses)
losses = losses[: len(eval_dataset)]
try:
perplexity = math.exp(torch.mean(losses))
except OverflowError:
perplexity = float("inf")
If it’s about the adding samples as this thread said.
