Data Science

These examples take quite a long time to run, and they make our documentation CI fail quite frequently due to timeout. It'd be nice to speed the up a little bit.

To contributors: if you want to work on an example, first have a look at the example, and if you think you're comfortable working on it and have found a potential way to speed-up execution time while preserving the educational message

Since SIP-9 in 2018, TypeScript has been a part of the Superset repo. Since SIP-36 in 2020 all new frontend code should be written in TypeScript. When modifying old functions/components, migrating to TypeScript is appreciated, but n

Problem: Currently JsonLoggerCallback.handle_result will load in the entirety of the existing results, append the new result, and then rewrite the entire file. This may not scale when running long-running jobs or jobs with large results.

Summary

Aesthetically trivial, yet I've spotted a discrepancy with font sizes in our tooltip (front-end + back-end screenshots below).
I believe sections #1 and #2 should have the same font size?

This is a minor nit, but right now PyTorch Lightning seems to pin a very specific version of pyDeprecate==0.3.1. This is causing some dependency mismatches on our-end, since we have a separate dependency in our environment that relies on pyDeprecate==0.3.2.

In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange. I set max_date_allowed = datetime.today().date(), but in the calendar, yesterday is the maximum date allowed. I see it in my apps, and it is also present in the first example on the DatePickerRange documentation page.

E

Python 3.10 added suggestions for AttributeError and NameError in the error messages. It seems the suggestions are not stored in the exception object but calculated when Error is displayed. There is a note that that this won't work with IPython but it will be good to see if it's feasible. Opening an issue for discussion.

Bug summary

imshow extents cannot be expressed with units.

Code for reproduction

fig, ax = plt.subplots()
dates = np.arange("2020-01-01","2020-01-10 23:00", dtype='datetime64[h]')
ys = np.random.random(dates.size)
arr = np.random.random((10, 10))

ax.imshow(arr, extent=[dates[0], dates[1], 0, 10])

Although the results look nice and ideal in all TensorFlow plots and are consistent across all frameworks, there is a small difference (more of a consistency issue). The result training loss/accuracy plots look like they are sampling on a lesser number of points. It looks more straight and smooth and less wiggly as compared to PyTorch or MXNet.

It can be clearly seen in chapter 6([CNN Lenet](ht

I typically used compressed datasets (e.g. gzipped) to save disk space. This works fine with AllenNLP during training because I can write my dataset reader to load the compressed data. However, the predict command opens the file and reads lines for the Predictor. This fails when it tries to load data from my compressed files.
