C2W1 Cats vs Dogs: [Errno 17] File exists: '/tmp/tmpohn3lgwf'

I get the following error:

Details of failed tests for create_train_test_dirs

Failed test case: There was an error grading this function. Details shown in ‘got’ value below:.
Expected:
no exceptions,
but got:
[Errno 17] File exists: ‘/tmp/tmpohn3lgwf’.

Here is my code:

root_dir = ‘/tmp/cats-v-dogs’
if os.path.exists(root_dir):
shutil.rmtree(root_dir)

def create_train_test_dirs(root_path):
os.makedirs(root_path)
sd1=[“training”, “testing”]
sd2=[“dogs”,“cats”]
for i in sd1:
path=os.path.join(root_path,i)
os.makedirs(path)
for j in sd2:
os.makedirs(os.path.join(path,j))

try:
create_train_test_dirs(root_path=root_dir)
except FileExistsError:
print(“You should not be seeing this since the upper directory is removed beforehand”)

Everything works perfectly, but I don’t know how to eliminate the error. Please help

did your issue got resolved? I am getting the same error

Anyone have Information on this? I am getting a similar error.

Hi all, the problem here is that you are creating the root directory with os.makedirs(root_path) which the grader assumes already exists. This is a bug and we will fix it shortly. If you delete that line you will get full score.

5

But isn’t it necessary to create that directory? Why does the function assume it exists?
If I delete it, I get this error:
The system cannot find the path specified: ‘cats-v-dogs\training’

My comment was misleading, what I meant was that learners should avoid creating the top level directory directly (since os.makedirs creates all intermediate-level directories needed to contain the leaf directory). When I mentioned the function assumes it exists I meant within the grader not the assignment (since they run in different envs). Will edit my original comment.

This happens due to a bug in the grader which we will fix shortly. For now please avoid creating the top level directory directly and you should be fine.

I deleted that line and get this error:
[Errno 2] No such file or directory: '/tmp/

@Johnny_Dukovich would you mind sharing your function? It is hard trying to help if I don’t know the details of your implementation

Hi,
Is the issue resolved sir or you are still facing it?
Many thanks

Hi,
I still have this issue

I used
os.makedirs(os.path.join(root_path, “training”), exist_ok=True)
os.makedirs(os.path.join(root_path, “training/cats”), exist_ok=True)
os.makedirs(os.path.join(root_path, “training/dogs”), exist_ok=True)

os.makedirs(os.path.join(root_path, “validation”), exist_ok=True)
os.makedirs(os.path.join(root_path, “validation/cats”), exist_ok=True)
os.makedirs(os.path.join(root_path, “validation/dogs”), exist_ok=True)

and still have the same bug:
FileNotFoundError: [Errno 2] No such file or directory: ‘/tmp/PetImages/Cat//tmp/PetImages/Cat/9341.jpg’
