What does stopping the runtime while uploading a dataset to Hub cause?

Asked 2022-Mar-24 at 01:06

I am getting the following error while trying to upload a dataset to Hub (dataset format for AI) S3SetError: Connection was closed before we received a valid response from endpoint URL: "<...>".

So, I tried to delete the dataset and it is throwing this error below.

CorruptedMetaError: 'boxes/tensor_meta.json' and 'boxes/chunks_index/unsharded' have a record of different numbers of samples. Got 0 and 6103 respectively.

Using Hub version: v2.3.1

ANSWER

Answered 2022-Mar-24 at 01:06

Seems like when you were uploading the dataset the runtime got interrupted which led to the corruption of the data you were trying to upload. Using force=True while deleting should allow you to delete it.

For more information feel free to check out the Hub API basics docs for details on how to delete datasets in Hub.

If you stop uploading a Hub dataset midway through your dataset will be only partially uploaded to Hub. So, you will need to restart the upload. If you would like to re-create the dataset, you can use the overwrite = True flag in hub.empty(overwrite = True). If you are making updates to an existing dataset, you should use version control to checkpoint the states that are in good shape.

QUESTION

Does Hub support integrations for MinIO, AWS, and GCP? If so, how does it work?

Asked 2022-Mar-19 at 16:28

I was taking a look at Hub—the dataset format for AI—and noticed that hub integrates with GCP and AWS. I was wondering if it also supported integrations with MinIO.

I know that Hub allows you to directly stream datasets from cloud storage to ML workflows but I’m not sure which ML workflows it integrates with.

I would like to use MinIO over S3 since my team has a self-hosted MinIO instance (aka it's free).

ANSWER

Answered 2022-Mar-19 at 16:28

Hub allows you to load data from anywhere. Hub works locally, on Google Cloud, MinIO, AWS as well as Activeloop storage (no servers needed!). So, it allows you to load data and directly stream datasets from cloud storage to ML workflows.

You can find more information about storage authentication in the Hub docs.

Then, Hub allows you to stream data to PyTorch or TensorFlow with simple dataset integrations as if the data were local since you can connect Hub datasets to ML frameworks.

There is a simple formula that maps Turtle to Net Pos. The calculation can be expressed as a sum of geometric series times base_quantity, yielding the function f below.

Generate the all possible unique peptides (permutants) in Python/Biopython

Asked 2021-Dec-01 at 07:07

I have a scenario in which I have a peptide frame having 9 AA. I want to generate all possible peptides by replacing a maximum of 3 AA on this frame ie by replacing only 1 or 2 or 3 AA.

The frame is CKASGFTFS and I want to see all the mutants by replacing a maximum of 3 AA from the pool of 20 AA.

we have a pool of 20 different AA (A,R,N,D,E,G,C,Q,H,I,L,K,M,F,P,S,T,W,Y,V).

I am new to coding so Can someone help me out with how to code for this in Python or Biopython.

output is supposed to be a list of unique sequences like below:

CKASGFTFT, CTTSGFTFS, CTASGKTFS, CTASAFTWS, CTRSGFTFS, CKASEFTFS ....so on so forth getting 1, 2, or 3 substitutions from the pool of AA without changing the existing frame.

Ok, so after my code finished, I worked the calculations backwards,

Case1, is 9c1 x 19 = 171

Case2, is 9c2 x 19 x 19 = 12,996

Case3, is 9c3 x 19 x 19 x 19 = 576,156

That's a total of 589,323 combinations.

Here is the code for all 3 cases, you can run them sequentially.

You also requested to join the array into a single string, I have updated my code to reflect that.

Asked 2021-Aug-11 at 15:55

I have a table with features that were used to build some model to predict whether user will buy a new insurance or not. In the same table I have probability of belonging to the class 1 (will buy) and class 0 (will not buy) predicted by this model. I don't know what kind of algorithm was used to build this model. I only have its predicted probabilities.

Question: how to identify what features affect these prediction results? Do I need to build correlation matrix or conduct any tests?

ANSWER

Answered 2021-Aug-11 at 15:55

You could build a model like this.

x = features you have. y = true_lable

from that you can extract features importance. also, if you want to go the extra mile,you can do Bootstrapping, so that the features importance would be more stable (statistical).

Install pandas_cub

This repository contains a detailed project that teaches you how to build your own Python data analysis library, pandas_cub, from scratch. The end result will be a fully-functioning library similar to pandas.
I recommend creating a new environment using the conda package manager. If you do not have conda, you can download it here along with the entire Anaconda distribution. Choose Python 3. When beginning development on a new library, it's a good idea to use a completely separate environment to write your code.

All docstrings can be retrieved programmitcally with the __doc__ special attribute. Docstrings can also be dynamically set by assigning this same special attribute a string. This method is already completed and automatically adds documentation to the aggregation methods by setting the __doc__ special attribute.
