paddle-mobile将开发一个新的版本，为了：

• 支持Paddle Fluid
• 更小的体积
• 更快的速度
• 更广泛地支持各种arm设备和终端平台

因此，paddle-mobile将会进行一次完全的重构，从框架设计到代码开发。在新版本开发完成后，将会删除原有mobile-deep-learning的代码。新版本开发期间，代码将放置在paddle-mobile repo的一个子目录下。对于子目录的命名，目前有3个候选，希望大家投票：

• 👍 zygote
• 👎 paddle
• ❤️ fluid

有更好的建议，请回复issue。相关issue：#121
另外，待新版本代码开发完成，移除老版本mobile-deep-learning代码后，新版本代码将移出子目录，直接放置在paddle-mobile repo下面。

After spending some time to debug it, I discovered that the project cannot be compiled on MacOS if -DCLANG_SUFFIX="-9" is passed. I have llvm@9 installed from brew and it gives the following error:

-- The C compiler identification is Clang 9.0.1
-- The CXX compiler identification is unknown
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - failed
-- Check for work

Resurrecting the second bullet from #1334

Running this code causes D19 to idle high and not oscillate. Removing D30 from pins_temp corrects the issue. No errors are flagged. D30 and D19 share TC4_WO1, but have different TCC peripherals.

import board
import time
import pwmio

pins_temp = [ board.D30, board.D19]
pwm_pins = []
for pin in pins_temp:
    p = pwmio.PWMOut(pin, frequency=10, duty_cycle=0x7fff, variable_frequenc

On Linux, packets that stay local to the machine (moving from the host to a container for example) don't always have their checksum computed, see for example https://patchwork.ozlabs.org/patch/261822/.
The proper fix would be to check for TP_STATUS_CSUMNOTREADY, but an easy workaround is to have a way to change the ChecksumCapabilities or DeviceCapabilities.
