SSD mobilenet model does not detect objects at longer distances

白昼怎懂夜的黑 提交于 2020-01-29 05:20:05
问题 I have trained an SSD Mobilenet model with custom dataset(Battery). Sample image of the battery is given below and also attached the config file which I used to train the model. When the object is closer to the camera(tested with webcam) it detects the object accurately with probability over 0.95 but when I move the object to a longer distance it is not getting detected. Upon debugging, Found that the object gets detected but with the lower probability 0.35 . The minimum threshold is set to 0

How to determine storage type (SSD drive or HHD .mechanical drive), using C language

。_饼干妹妹 提交于 2020-01-23 16:47:07
问题 How can I, from a C program, read the hardware information of a drive? (I.e. to determine if the drive is an SSD or a mechanical disk.) 回答1: SSD are supposed to identify themselves as non-rotative. For linux, as example, you can get the info via sysfs: cat /sys/block/sda/queue/rotational If it returns 0, you have SSD... 回答2: Have you considered doing a read/write test to try to determine capabilities ? 回答3: You can use the GetDriveType Method from the win32 library, and you might be able to

NASM: how to access ssd drive correctly?

问题 I need to access SSD drive with NASM 16-bit code. When accessing regular hard drive, need to set registers AX, DX, CX to choose Cylinder/Track/Sector/Number of sectors ( AH - to choose read sector function, DL - to choose drive number, CH - to choose cylinder, DH - to choose side on disk, CL - to choose sector on track, AL - to choose number of sectors). However, I suppose SSD disk has some other structure, so how to access them correctly? 回答1: Assuming translation of fake geometry into LBA

Intel NVMe drive Performance degradation with xfs filesystem with sector size other than 4096

问题 I am working with NVMe card on linux(Ubuntu 14.04). I am finding some performance degradation for Intel NVMe card when formatted with xfs file system with its default sector size(512). or any other sector size less than 4096. In the experiment I formatted the card with xfs filesystem with default options. I tried running fio with 64k block size on an arm64 platform with 64k page size. This is the command used fio --rw=randread --bs=64k --ioengine=libaio --iodepth=8 --direct=1 --group

Converting SSD to frozen graph in tensorflow. Which output node names must be used?

戏子无情 提交于 2019-12-22 10:57:03
问题 I trained SSD using TensorFlow Object Detection API as described here. It produces a ckpt, meta and index file. In order to run it on my images I tried to check the demo code. It requires that the model be converted to frozen graph. I tried to convert my model to a frozen inference graph as described here. In that program I have to provide output node names. I could not figure out the name of the node in the SSD model which must be used here. Please help. I tried 'num_detections:0',

Will SSD drive make maven builds faster?

好久不见. 提交于 2019-12-22 09:19:47
问题 Good post here says speed better with SSD drive for Eclipse work. But my slow part is mostly for maven builds. I have project with 1600+ classes. It take 2-3 min for a clean build with maven. I wonder if SSD drive will make it faster? Because SSD drive is big improvement on reads, but smaller improvement on writes as I understand. I wonder if anyone has experimented with this? 回答1: SSD write speed is slower than read speed but you don't have dsk access latency to pay, so will nearly always be

Speed up compile time with SSD

家住魔仙堡 提交于 2019-12-21 06:56:16
问题 I want to try to speed up my compile-time of our C++ projects. They have about 3M lines of code. Of course, I don't need to always compile every project, but sometimes there are lot of source files modified by others, and I need to recompile all of them (for example, when someone updates an ASN.1 source file). I've measured that compiling a mid-project (that does not involves all the source files) takes about three minutes. I know that's not too much, but sometimes it's really boring waiting

SSD drives not accessible in EC2 ubuntu Instances

问题 In the following EC2 instance types which have SSD drives r3.2xlarge r3.4xlarge i2.xlarge When I login through SSH, I am unable to see the SSD drives. I was trying "df -h". I have tried reboot, but that did not help. tried to terminate and create a new instance that also does not help. Suggesting that its not one-off issue. 回答1: I found one solution by trying the steps suggested for adding EBS volumes to Ubuntu instnaces Below are my steps: sudo mkfs.ext4 /dev/xvdb sudo mkdir -m 000 /mnt #

Detecting SSD in Windows

时光总嘲笑我的痴心妄想 提交于 2019-12-18 03:57:33
问题 I would like to change the performance and behaviour of my C++ application, according to whether the system drive is an SSD or not. Example: With SSD, I want my gameserver application to load each map fully, with all objects in order to maximize performance. With HDD, I want my gameserver application to load only the essential objects and entities in each map, with no external objects loaded. I've seen http://msdn.microsoft.com/en-gb/library/windows/desktop/aa364939(v=vs.85).aspx, which is a
