Results in file not found error GZIP HASH-LIB

[Dharmogata]

can anyone help me understand why this is resulting in a file not found error, trying to fetch the datasets from the mnist dataset to follow along with someone else doing the same thing, on their end this exact code works fine.

def fetch(url):
import requests, gzip, os, hashlib, numpy
fp = os.path.join("/tmp", hashlib.md5(url.encode('utf-8')).hexdigest())
if not os.path.isfile(fp):
with open(fp, "rb") as f:
dat = f.read()
else:
with open(fp, "wb") as f:
dat = requests.get(url).content
f.write(dat)
return numpy.frombuffer(gzip.decompress(dat), dtype=np.uint8).copy()
X_train = fetch("http://yann.lecun.com/exdb/mnist/train-images-idx3-ubyte.gz")[0x10:].reshape((-1, 28, 28))
Y_train = fetch("http://yann.lecun.com/exdb/mnist/train-labels-idx1-ubyte.gz")[8:]
X_test = fetch("http://yann.lecun.com/exdb/mnist/t10k-images-idx3-ubyte.gz")[0x10:].reshape((-1, 28, 28))
Y_test = fetch("http://yann.lecun.com/exdb/mnist/t10k-labels-idx1-ubyte.gz")[8:]

in fetch(url)
6 print(fp)
7 if not os.path.isfile(fp):
----> 8 with open(fp, "rb") as f:
9 dat = f.read()
10 else:

FileNotFoundError: [Errno 2] No such file or directory: '/tmp/23278f029ff68f1e993776e500ce06b9'

This can be fixed by removing the '/' before 'temp' when joining the path
i.e.
fp = os.path.join("tmp", hashlib.md5(url.encode('utf-8')).hexdigest())
