指令打错了，仔细检查文件名，路径没对

[qq1243196045]

我也是这个错误，路径是复制的...用命令行就不报错，在IDE里面就报错（-f 设置了default值），仔细想想IDEtrain.py在tools下面，如果要用相对路径的话要..到项目根目录（pycharm的目录结构问题，VSCODE没有这个问题），或者在run/edit-configurations下修改working dir为项目根目录......

还真是，我一开始在pycharm的Terminal里面输入指令： python tools/train.py -f /exps/example/yolox_voc/yolox_voc_s.py -d 1 -b 8 --fp16 -o 结果报了下面这个错：

Traceback (most recent call last):

current_exp = importlib.import_module(os.path.basename(exp_file).split(".")[0])#importlib.import_module()导入括号内给出的python文件 ; os.path.basename()返回path最后的文件名。

接着修改指令中-f 后面的地址参数：python tools/train.py -f exps/example/yolox_voc/yolox_voc_s.py -d 1 -b 8 --fp16 -o，就跑起来了。原来是多加了一个 "/"导致的错误。
