标题: 使用pre_compile=True building model失败
在rknn.build设置pre_compile=True后，报错。设置代码节选如下：
  1.         # Build model
  2.         print('--> Building model')
  3.         ret = rknn.build(do_quantization=True, pre_compile=True, dataset='./dataset.txt')
  4.         if ret != 0:
  5.             print('build model failed.')
  6.             exit(ret)
  7.         print('done')
复制代码
报错结果如下：

复制代码/tmp 目录下无  tmp0s82ra97/gen_nbg  请问这个目录文件如何生成的？需要自己添加吗？在sdk中有没有？
/home/rv1109/external/rknn-toolkit/examples/darknet/yolov3_rknn/*.nb'及 /*.dat  两个文件也不存在，这两个文件需要获取吗？如何获取？

看了《Rockchip_Trouble_Shooting_RKNN_Toolkit_V1.4.0_CN.pdf》中关于rknn.build()设置pre_compile=True报错，其中写道需要确认
请确认:
1) 系统装有 gcc 编译工具链
2) 模型的名称只包含“字母”、“数字”、“_”,特别注意有些复制过来的模型名称
会自动加上”(1)”,这时会失败。也可以升级到 1.3.0 或之后的版本,由 RKNN Toolkit 自
动处理这些特殊字符。
如果不属于上述情况,可以尝试使用 export_rknn_precompile_model 接口从板子上导出
预编译模型。
系统为ubuntu18.04装有gcc，rknn-toolkit  1.6.0,

使用export_rknn_precompile_model的代码如下：
  1.     print('--> init runtime')
  2.     # ret = rknn.init_runtime()
  3.     ret = rknn.init_runtime(target='rv1126', device_id='3166854b086a700f', rknn2precompile=True)
  4.     if ret != 0:
  5.         print('init runtime failed.')
  6.         exit(ret)
  7.     print('done')



  11.     print('--> export pre-compile model')
  12.     # Note:the rknn2precompile must be set True when call init_runtime
  13.     ret = rknn.export_rknn_precompile_model('./test_pre_compile.rknn')
  14.     if ret != 0:
  15.         print('export pre-compile model failed.')
  16.         exit(ret)


  19.     rknn.release()
复制代码仍然报上述错误，如下所示：
  1. (venv) wenji-G3:~/rv1109/external/rknn-toolkit/examples/darknet/yolov3_rknn$ python test.py

请问这种情况应该如何解决？

已发现是编译器的问题，在环境里看到
export PATH=$PATH:~/rv1109/external/RKNPUTools/rknn-api/Linux/rknn_api_sdk/gcc-linaro-6.3.1-2017.05-i686_aarch64-linux-gnu/bin
export PATH=$PATH:~/rv1109/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin
环境路径没有问题，在rv1109目录下搜索各种build.sh文件中，没有发现gcc-linaro-6.3.1-2017.05-i686_aarch64-linux-gnugcc这个路径，都是上边两条正确的路径，报错的编译器后缀带有gcc。请问我该如何解决这个问题？
