Q&A
現在convert.pyを実行するために画像データとテキストデータを作った状態でconvert.pyを実行しようとすると
['out19.csv', 'out11.csv', 'out16.csv', 'out17.csv', 'out12.csv', 'out13.csv', 'out18.csv', 'out14.csv', 'out15.csv', 'out10.csv', 'out6.csv', 'out2.csv', 'out9.csv', 'out7.csv', 'out5.csv', 'out3.csv', 'out1.csv', 'out8.csv', 'out4.csv', 'out0.csv', 'out26.csv', 'out27.csv', 'out28.csv', 'out23.csv', 'out24.csv', 'out22.csv', 'out21.csv', 'out25.csv', 'out20.csv']
Input:labels/stopsign_original/out19.csv
Output:labels/stopsign/out19.csv
47,103,470,581,tops
['47,103,470,581,tops\n']
Traceback (most recent call last):
File "convert.py", line 78, in <module>
xmax = elems[1]
IndexError: list index out of range
上記のようなエラーが出てしまいます。
解決策を教えてください。
お願いします。
これだけでは足りないと思うので解決する為に必要な情報があったら教えてください。
環境はgooglecolabです。

Python
1if(len(line) >= 2): 2 ct = ct + 1 3 print(line + "\n") 4 elems = line.split(' ') 5 print(elems) 6 xmin = elems[0] 7 xmax = elems[1]
lineの内容がカンマ区切りであるのに、スペースで分割しようとして失敗しています。
