The same thing occurred to me yesterday when I used Colab. A possible reason may be that the version of opencv-python(4.1.2.30) does not match opencv-python-headless(4.5.5.62). Or the latest version 4.5.5 may have something wrong...

I uninstalled opencv-python-headless==4.5.5.62 and installed 4.1.2.30 and it fixed.

How to measure energy usage in Xcode 13 / iOS15?

Asked 2022-Feb-23 at 00:43

I'd like to confirm the battery usage of an app I am developing on iOS, specifically on Xcode 13 and iOS 15. (Note: This app previously showed no issues with battery usage on previous versions of iOS.)

Previously, it seems that there were two ways to gather energy usage information:

#1. On the device under Settings > Developer > Logging

As per Apple's documentation described in the section titled "Log Energy Usage Directly on an iOS Device".
However, on iOS15, I can't find any options for logging under Developer or anywhere under settings even when searching.

#2. Profiling via Instruments using the "Energy Log" template

As per the same documentation from Apple described in the section "Use the Energy Diagnostics Profiling Template".
While it is still available in Xcode 12, this template is missing in Xcode 13. Naturally, it's also not possible to profile an iOS15 device with Xcode 12.

Digging through the Xcode 13 release notes, I found the following:

Instruments no longer includes the Energy template; use metrics reporting in the Xcode Organizer instead. (74161279)

When I access the Organizer in Xcode (12 or 13), select an app and click "Energy" for all versions of the app, it shows the following:

Apple's documentation for "Analyzing the Performance of Your Shipping App" says:

"In some cases the pane shows “Insufficient usage data available,” because there may not be enough anonymized data reported by participating user devices. When this happens, try checking back in a few days."

Well over a year into production and having sufficient install numbers, I have a feeling that waiting a few days might not do much.

I would like to determine if this is a bug in my app or a bug in iOS15. How can energy usage data be gathered using Xcode 13 on iOS 15?

...

ANSWER

Answered 2022-Feb-23 at 00:43

After contacting Apple Developer Technical Support (DTS) regarding this issue, they provided me with the following guidance.

Regarding "insufficient usage data available" for energy logs accessible via the Xcode organizer:

DTS indicated that they do not publish the thresholds for active users and usage logs would be expected to be present if you have more that a few thousand active users consistently on each version of your app. If your app meets this criteria and still does not show energy logs, DTS recommended opening a bug report with them.

Regarding how to collect energy log data for your app:

DTS recommended using MetricKit to get daily metric payloads. Payloads are delivered to your app every 24 hours and it is then possible to consume them and send them off device.

The instantiation of this is vey basic and can be as simple as:

I would propose to take a look in the RateLimiter direction. Maybe it does not work as expected, depending on the number of requests your application does over time. From the Javadoc for Ratelimiter: "It is important to note that the number of permits requested never affects the throttling of the request itself ... but it affects the throttling of the next request. I.e., if an expensive task arrives at an idle RateLimiter, it will be granted immediately, but it is the next request that will experience extra throttling, thus paying for the cost of the expensive task." Also helpful might be this discussion: github or github

I could imaginge there is some throttling adding up or other effect in the RateLimiter, i would try to play around with it and make sure this thing really works the way you want. Alternatively, consider using Spring @Scheduled to read from your queue. You might want to spice it up using embedded JMS for further goodies (message persistence etc).

This seems to be a bug in Tensorflow 2.7 when using model.save combined with the parameter save_format="tf", which is set by default. The layers RandomFlip, RandomRotation, RandomZoom, and RandomContrast are causing the problems, since they are not serializable. Interestingly, the Rescaling layer can be saved without any problems. A workaround would be to simply save your model with the older Keras H5 format model.save("test", save_format='h5'):

get cloudfront usage report via aws cli

Asked 2022-Feb-04 at 12:49

I have a bunch of Cloudfront distributions scattered across a number of AWS accounts. I'd like to get the Usage Reports for all Cloudfront distros across all AWS accounts.

Now, I have the change-account bit already automated, but I'm not sure how to get the CSV report via the AWS CLI.

I know I can do some ClickOps and download the report via the Cloudfront Console, like here:

but I can't find the command to get the report with the AWS CLI.

I know I can get the Cloudfront metrics via the Cloudwatch API but the documentation doesn't mention the API endpoint I should be querying.

Also, there's aws cloudwatch get-metric-statistics, but I'm not sure how to use that to download the Cloudfront Usage CSV Report.
