第十二周-----CityScapes尝试

主要想使用CityScapes尝试目标检测以及语义分析，但是最终出现很多没有见到过的问题，弄起来非常地麻烦。

根据教程下载了数据集以及models 

教程

由于使用的是windows环境所以只能尝试的使用。

但是在 sh convert_cityscapes.sh 时出现问题，找不到指定模块。解决：（首先看一下convert_cityscapes.sh文件内容）

# Script to preprocess the Cityscapes dataset. Note (1) the users should
# register the Cityscapes dataset website at
# https://www.cityscapes-dataset.com/downloads/ to download the dataset,
# and (2) the users should download the utility scripts provided by
# Cityscapes at https://github.com/mcordts/cityscapesScripts.
#
# Usage:
#   bash ./preprocess_cityscapes.sh
#
# The folder structure is assumed to be:
#  + datasets
#    - build_cityscapes_data.py
#    - convert_cityscapes.sh
#    + cityscapes
#      + cityscapesscripts (downloaded scripts)
#      + gtFine
#      + leftImg8bit
#

# Exit immediately if a command exits with a non-zero status.
set -e

CURRENT_DIR=$(pwd)
WORK_DIR="."

# Root path for Cityscapes dataset.
CITYSCAPES_ROOT="F:/ModelArts/cityscapesScripts"   #指定你的Cityscapes文件夹

# Create training labels.
python "${CITYSCAPES_ROOT}/cityscapesscripts/preparation/createTrainIdLabelImgs.py"  #根据上面文件夹可以运行这个py文件

# Build TFRecords of the dataset.
# First, create output directory for storing TFRecords.
OUTPUT_DIR="${CITYSCAPES_ROOT}/tfrecord"       #指定记得输出文件（tfrecord）
mkdir -p "${OUTPUT_DIR}"              #创建文件夹

BUILD_SCRIPT="${CURRENT_DIR}/build_cityscapes_data.py"    #运行这个py文件（这个py文件会在tfredord文件夹中产生训练模型）

echo "Converting Cityscapes dataset..."
python "${BUILD_SCRIPT}" \
  --cityscapes_root="${CITYSCAPES_ROOT}" \
  --output_dir="${OUTPUT_DIR}" \

在createTrainIdLabelImgs.py中出现找不到指定模块

 在运行就不会有问题了。
