我正在尝试通过终端执行以下给定命令：
translate bn en < '/home/agnihotri/results/Amader_Malda_4.jpg.txt'
py-translate库已成功安装。无论我执行任何命令，该错误均保持不变。
即使是像translate en <<< "hello world"这样的命令
但是，在执行过程中，我得到以下给定的错误：
> Traceback (most recent call last): File
> "/usr/local/lib/python3.6/dist-packages/translate/coroutines.py", line
> 170, in spool
> stream = yield GeneratorExit
在处理上述异常期间，发生了另一个异常：
> Traceback (most recent call last): File
> "/usr/local/lib/python3.6/dist-packages/translate/coroutines.py", line
> 145, in set_task
> task = yield GeneratorExit
在处理上述异常期间，发生了另一个异常：

请帮助。
