Getting filenotfound error when trying to open a h5 file-CodePudding

I have a h5 file that contains the "catvnoncat" dataset. when I try to run the following code, I get an error which I will include at the bottom. I have tried getting the dataset from three different sources to exclude to possibility of a corrupted file.

What I would like to know is what is causing the problem?

# My Code
import h5py
train_dataset = h5py.File('train_catvnoncat.h5', "r")

# The Error

CodePudding user response：

Your code is looking in the current directory which is not where the file is.

Based on the error message, it looks like you are on windows. Is the file 'train_catvnoncat.h5' in your Downloads folder? Find that file on your system and copy the full path. You can then update this:

train_dataset = h5py.File('train_catvnoncat.h5', "r")

to something that contains the full path. Similar to this:

train_dataset = h5py.File('C:/Users/Moshen/Downloads/train_catvnoncat.h5', "r")

Pay attention to the slashes and make sure you update the file path to the actual value.
