Jetson TX2的各种坑.md

最近在使用Jetson TX2 在跑实验，然后遇到下面问题，做笔记，记录一下。

内存出错无法，中断

# 出现下面那种错误
2019-01-11 19:41:46.959970: E tensorflow/stream_executor/cuda/cuda_driver.cc:1068] failed to synchronize the stop event: CUDA_ERROR_LAUNCH_FAILED

解决办法：

    config = tf.ConfigProto(allow_soft_placement=True)
    config.gpu_options.allow_growth = True #加多这一行
    sess = tf.Session(config=config)

出现failed to alloc 2304 bytes on host: CUDA_ERROR_UNKNOWN错误

• 跟上面的解决办法一样，使用config.gpu_options.allow_growth = True

nvidia-smi无法使用

使用sudo ~/tegrastats,GR3D表示GPU
