#DType
PyArrow dtypes in #Python #Pandas are nullable (with pd.NA):

s = Series([10, pd.NA, 30], dtype='int64[pyarrow]')

s is:

0 10
1
2 30
dtype: int64[pyarrow]

The dtype is int64, but allows nulls. (Use np.nan? It's turned into pd.NA.)

a D-type, better known as a dtype in the numpy community,

Thank you for making nse dtype like a true loser i Sm

You have a #Python #Pandas series with ints + NaN. You don't want float forced on you.

Solution: Use the "extension" type Int64 (note Initial Caps) and pd.NA:

s = Series([10, pd.NA, 30], dtype='Int64') # must name explicitly

s is:

0 10
1
2 30
dtype: Int64

Values in a #Python #Pandas series all have the same dtype.

np.nan is a float, so (1) the series gets a float dtype, or
(2) it's "object," meaning "something unspecific."

Annoying for integers. Awful for other types.

For this, we need nullable types! (Coming tomorrow...)

Did you know that on Argilla, we’re adding a new feature to export labeled datasets directly to the Hugging Face Hub? 🤔

We’re leveraging the Hugging Face datasets library for seamless integration, including defining span labeling

Stay tuned for the release!🧠✨

nice attention :) is it causal? and multiheaded, i assume?quantized? what dtype? btw is it sparse? latent? is it fast, memory-efficient, and exact? :3 oh with io-awareness? are yr queries grouped? ^^ w/ a sliding window? oh oh is it gated? is it linear? is ur positional encoding rotary? :D

"write this same function (dtype x arch) more times and test it" is almost perfectly suited for the intern bot

i am mostly confident i can do this because there is already a good cuda kernel for fwht it just only works on one dtype on one gpu arch

bizarre; what's the dtype? bf16?

`torch_dtype` is deprecated! Use `dtype` instead!

Would recommend github.com/patrick-kidg... as an updated+better version!

(Even for pytorch, despite the name.)

massive shoutout to pandas for changing the dtype of an int column to a float when accessing a row, which makes a series (because a series can't have mixed types)... hence breaking a filename I needed to get out of the int 😑

Published arro3-core v0.6 with wider dtype support for converting numpy ndarrays to Arrow. It now additionally supports:
- datetime64
- timedelta64
- fixed-width strings/bytes
- variable-width strings
- object arrays of str/bytes

And the Python wheel is still just 2.5MB!

First modification : Add an RS-232 transceiver and 9 way Dtype for the second SIO channel.

ok so matching the dtype (fp64), resolution (4096^2), network size (272 params), & training iterations (1000) of the original paper gives me... 7 and a half hours to render a single frame on my 3090 🙃

You can set a #Python #Pandas series index with set_axis. This returns a new series with the new index applied:

s = pd.Series([10, 20, 30], index=list('abc'))

(
s
.set_axis(list('qrs'))
.loc[['q', 's']]
) # q=10, s=30

s.index # still Index(['a', 'b', 'c'], dtype='str')

Polars 2.0 RC2 is out. Breaking changes first: a new Map dtype, cut/qcut deprecated, Parquet ENUM now reads as String. Then the optimizer work: dynamic predicates for hash joins, predicates derived from join conditions. Run your pipelines against it now.

random_vector = torch.randn(HIDDEN_DIM, dtype=torch.float32, device=device)

noise = torch.randn(VOCAB_SIZE, HIDDEN_DIM, dtype=torch.float32, device=device) * INIT_SIGMA

init = random_vector + noise

model.transformer.wte.weight[:] = init.to(torch.bfloat16)

↑ I think this does it. Maybe. Not sure.

If your dtype is too small, operations on your #Python #Pandas series will fail:

s = Series([10, 20, 30], dtype='int8')
s + 100

Returns:

0 110
1 120
2 -126 # 🤯
dtype: int8

This does give an error:

s + 500
OverflowError: Python integer 500 out of bounds for int8
