The Mixed Time-Series chart type allows for configuring the title of the primary and the secondary y-axis.
However, while only the title of the primary axis is shown next to the axis, the title of the secondary one is placed at the upper end of the axis where it gets hidden by bar values and zoom controls.

How to reproduce the bug

  1. Create a mixed time-series chart
  2. Configure axi

Description

Per https://discuss.ray.io/t/how-do-i-sample-from-a-ray-datasets/5308, we should add a random_sample(N) API that returns N records from a Dataset. This can be implemented via a map_batches() followed by a take().

Use case

Random sample is useful for a variety of scenarios, including creating training batches, and downsampling the dataset for

Problem

See #3856 . Developer would like the ability to configure whether the developer menu or viewer menu is displayed while they are developing on cloud IDEs like Gitpod or Github Codespaces

Solution

Create a config option

showDeveloperMenu: true | false | auto

where

  • true: always shows the developer menu locally and while deployed

🐛 Bug

tuner.scale_batch_size finds the suitable batch size and update the batch size of the model AND datamodule.
For the model, tuner.scale_batch_size updates the batch size in the model regardless of model.batch_size and model.hparams.batch_size.

However, for the datamodule, tuner.scale_batch_size updates datamodule.batch_size only, and keep datamodule.hparams.batch_size

Bug summary

When the build gets to https://github.com/matplotlib/matplotlib/blob/main/src/_tkagg.cpp#L262-L273 on Cygwin, the build fails with a few goto crosses initialization warnings, which are easy to fix, and two error: ‘PyErr_SetFromWindowsErr’ was not declared in this scope, which are less easy to fix.

do not mention the issues with reloading modules with enums:

  • Enum and Flag are compared by identity (is, even if == is used (similarly to None))
  • reloading a module, or importing the same module by a different name, creates new enums (look the same, but are not the same)

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

Describe the issue:
During computing Channel Dependencies reshape_break_channel_dependency does following code to ensure that the number of input channels equals the number of output channels:

in_shape = op_node.auxiliary['in_shape']
out_shape = op_node.auxiliary['out_shape']
in_channel = in_shape[1]
out_channel = out_shape[1]
return in_channel != out_channel

Is your feature request related to a problem? Please describe.
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.
