What do you like best about Weights & Biases?

I like the flexibility to log custom parameters, and the colorful comparisons between models in for instance confusion matrices. Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

There are a couple of features I would have liked, such as the ability to set a global normalization flag, or controlling which windows stay on screen on reload, maybe these features exist, in that case I just haven't been able to find them Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

We build image classification software, and for that it is very useful to track model performance Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

We are a small team of 15 researchers. After the years of usage tensorboard, we decided to try online tools. We tried a few of them and find out that WandB suits us best. We really like easy of use, the fact that experiments are easily sharable, and hyperparameter sweep option. Also the option to tag all your experiments and subsequent filtration of them is also great. Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

WandB provides an option to create a report from your experiments. It would be nice to use these reports in our papers, however, during the review period, papers should be anonymized but there is no option to anonymize the reports. Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

Experiments sharing and logging Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

I really can't resize images and masked images the way I want inside the GUI and looking at images on mobile is quite a nightmare Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

Logging my training runs. I could achieve the same result with tensorboard (and alike) + saving images and masks and periodically generating a webpage that shows them, but W&B already offers that and much more Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

The hosted aspect is great and if you avoid storing large artifacts, too many histograms, or too many images, it's very cheap or free even for heavy usage. I often run training on remote systems and checking the eval outputs remotely can be a pain with other software like TensorFlow. You need to be sure to run the server on your instance to view the dashboard. With W&B you get comparably powerful features, and you don't need to do anything but run your train script. In addition to hosting, the Sweeps functionality is excellent for hyper-parameter sweeping and pre-determined groups of runs in multi-task settings. Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

Some UI elements, like the Runs data table, can be laggy, and sometimes the auto-refresh seems finicky. Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

W&B helps track and debug my experiments. I use it for developing new models, observing loss scales and adjusting them so they're in compatible ranges, detecting and addressing gradient instabilities such as vanishing or exploding. I also use it for hyper-parameter searching to find the best values for my training runs. Additionally, I use the Sweeps functionality for coordinating runs that involve many related models that are deployed together. Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

Ease of setting it up, the dashboard is pretty much each to use and allows to visualize a wide range of features at once. The integration is pretty much solid and works out of box for any script that I worked on Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

I used to pre train certain checkpoints in a sequential manner or sometimes my runs used to break in between due to memory/connection issues from there on it was quite difficult to visualize all the previous run in a single curve using the dashboard, setting the x axis as wall time helped but the curve was still not a single continuous graph Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

In some of my experiments I wanted to visualize how the grad norm varies with train iter or how does the learning rate scheduler affect the perplexity of the model that I am working on, wandb makes doing these experiments much easier Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

The best thing about W&B is that you don't need to think about performance visualization anymore. W&B handles that for you, no matter how many metrics you have or how complex they are. It's also very simple to use! Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

Can't think of anything that I dislike, my experience has been very positive until now. Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

Helps a lot with visualization and performance tracking. Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

The ability to track everything including gradients is a wonderful aspect. Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

One problem is if there's a zombie wandb process and I try to kill it, it makes other functioning trainig runs terminate. Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

To keep track of all the experiments and look at the comparisons anytime.

Also share the plots and reports with the rest of the world. Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

I like the WEB UI, especially the manipulation of plots and reports as they simplify and visualize many metrics and parameters.

I also like the artifactory and the model registry, they help manage the countless number of models created during an ML/DL project.

Sweep management is also cool! We build an automation tool around it that simplifies ML sweeps and thus helps us get better results.

Finally, I love the prompt and kind assistance we (Nvidia) get on the dedicated Slack channel. Really appreciated! Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

Not too much actually :)

I guess sometimes the web UI is a bit slow. Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

It solves the management of many (many many) ML experiments; helps us improve our KPIs and track this improvement.

This is benefiting us by saving a lot of time on taking dev decisions based on results (i.e., decide on some algo change, set of hyper parameters). Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

The online API is really helpful to organize results and projects. Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

In the online website, the graphs showing evolution of a metric for example can't be dezoomed easily with the scroll wheel and we can't move in the graph after zooming. Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

It stores online my results and shows in live the logs. (without the need to run another command to visualize the results or refresh a page) Review collected by and hosted on G2.com.

What do you like best about Weights & Biases?

Its easy and seamless integration with PyTorch lightening and simple API usage. The model (artifact) and logs logging also help me trace back a model that was training months ago. Review collected by and hosted on G2.com.

What do you dislike about Weights & Biases?

Nothing as of now. Would appreciate more dark modes and API control to give experiment names, rather than having my experiment named 'Tasty-Aadvark'. Review collected by and hosted on G2.com.

What problems is Weights & Biases solving and how is that benefiting you?

Having all my training sessions accessble from single site, is the biggest benefit. Also, saving logs, training meta is quite helpful too. Review collected by and hosted on G2.com.
