[Tensorflow] API
2018. 7. 26. 10:40
공식사이트 : https://www.tensorflow.org/?hl=ko
- tf.placeholderrnn
- dtype: The type of elements in the tensor to be fed.
- shape: The shape of the tensor to be fed (optional). If the shape is not specified, you can feed a tensor of any shape.
- name: A name for the operation (optional).
- tf.contrib.rnn.BasicLSTMCell
일부 사용하는 arg 를 기입해놈
- num_units : int 형의 유닛 갯수
- state_is_tuple : true 일시 두개의 state 를 돌려주고 false 일시 하나의 state로 돌려준다.
- tf.nn.dynamic_rnn
arg
cell, inputs, sequence_length=None, initial_state=None, dtype=None, parallel_iterations=None, swap_memory=False, time_manjor=False, scope=None |
- cell :
returns:
(outputs,state)
- outputs : The RNN output Tensor
time_major == False (default) 일 경우 Tensor shaped : [batch_size, max_time, cell.output_size]
time_major == True 일경우 [max_time, batch_size, cell.output_size]
shape 모양이 바뀐다.

[rpi3] Kernel Download
2018. 7. 20. 10:07
라즈베리파이 커널 다운로드
Yocto recipes 파일의 커널 파일을 찾아보자
/home/kj/RPI3/AGL_RPI3/meta-raspberrypi/recipes-kernel/linux
해당 파일들은 다음과 같다.
linux-raspberrypi linux-raspberrypi_4.9.bb linux-raspberrypi-dev linux-raspberrypi-dev.bb linux-raspberrypi.inc linux-rpi.inc
linux-raspberrypi_4.9.bb 파일의 내용
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:" LINUX_VERSION ?= "4.9.50" SRCREV = "46e2d4d1bd2c17e2f84dd90768321ee0bbaa6b8a" SRC_URI = "git://github.com/raspberrypi/linux.git;branch=rpi-4.9.y" require linux-raspberrypi.inc # A LOADADDR is needed when building a uImage format kernel. This value is not # set by default in rpi-4.8.y and later branches so we need to provide it # manually. This value unused if KERNEL_IMAGETYPE is not uImage. KERNEL_EXTRA_ARGS += "LOADADDR=0x00008000" |
ERNEL_EXTRA_ARGS += "LOADADDR=0x00008000"
defconfig 파일을 참조하며
라즈베리파이3의 경우 KERNEL_DEFCONFIG_raspberrypi3-64 ?= "bcmrpi3_defconfig" 파일을 참조한다.
require linux-rpi.inc
inherit linux-raspberrypi-base
파일을 참조한다.
커널 옵션 defconfig 활성화를 아래와같이 변경하는 것으로 추정된다.
