一、报错展示

好家伙！一直这样循环报错

Traceback (most recent call last):
File "D:\anaconda3\envs\py36\lib\runpy.py", line 193, in _run_module_as_main

ModuleNotFoundError: No module named 'labelme'

二、解决办法

1.已解决

不得不说这个坑挖的对于我而言，心塞塞啊！！！

运行的原代码：

import os
path = 'E:\\data\\test00\\json\\'
# path是你存放json的路径
json_file = os.listdir(path)
for file in json_file:os.system("python D:\\anaconda3\\Scripts\\labelme_json_to_dataset.exe %s" % (path + file))    #遍历所有画好json文件，转换json文件

改过后的代码：

import os
# import json
# import labelmepath = 'E:\\data\\test01\\json_ntree\\'  # path是你存放json的路径
json_file = os.listdir(path)
for file in json_file:os.system("D:\\anaconda3\\Scripts\\labelme_json_to_dataset.exe %s" % (path + file))

区别：将路径上面的python去掉了，至于原因暂时我还不打算花时间现在就研究，解决了就好！能运行就很棒！

2.尝试过的解决办法【可能对其他小伙伴有用】

网上冲浪良久都没有发现和我这个问题一样的文章，尝试过以下方法：

（1）在安装anaconda时未添加环境变量，于是快马加鞭赶紧添加环境变量！

显然回来的时候她依旧不鸟我，照旧报她的错！【此处不展示如何添加的，如果未添加，建议查找大神的文章进行添加，那样心里舒坦些】

（2）想过是否是labelme没有安装成功。

显然不出所料的！安装成功了，报错依旧。泪奔！！！

（3）终于对源代码下了手！

这时候恰巧我看到了一篇文章，在这里感谢这位大神的慷慨奉献，虽然我还是依旧报错。

首先，找到shape.py文件，

其次，修改如下地方：

def polygons_to_mask(img_shape, polygons, shape_type=None):logger.warning("The 'polygons_to_mask' function is deprecated, ""use 'shape_to_mask' instead.")return shape_to_mask(img_shape, points=polygons, shape_type=shape_type)
# 底下的注释便是要修改上面这行的
'''
def polygons_to_mask(img_shape, polygons):mask = np.zeros(img_shape[:2], dtype=np.uint8)mask = PIL.Image.fromarray(mask)if len(polygons)==1:polygons.append(polygons[0])xy = list(map(tuple, polygons))PIL.ImageDraw.Draw(mask).polygon(xy=xy, outline=1, fill=1)mask = np.array(mask, dtype=bool)return mask
'''

（4）对于转化为Json文件夹的小伙伴们，如果遇到一物多色的问题

可以参考赞！解决labelme一物多色问题【对于个人研究来说有效】这篇文章，如果你是天选之子，可能这篇文章对你有用，如果不是，那么更加恭喜你，老天还想让你再锻炼锻炼！奥利给！
