Hi, I am trying out DVC for the first time for my deep learning development pipeline. As mentioned in the [Version Data with DVC](https://youtu.be/kLKBcPonMYw) tutorial, I created a folder named “dataset” in the main directory and then I added some data into it. And then I used `dvc add dataset` to track the dataset. After that, I included “dataset” folder in the .gitignore to untrack the dataset with git. Then I setup Azure storage blob for my remote data repo. After adding some more data, I wanted to go back to the original version of the data so I checkout to that git commit and then used `dvc checkout` command. Then this error comes up. ```auto +--------------------------------------------------+ | | | Update available 1.10.2 -> 1.11.10 | | Run `apt-get install --only-upgrade dvc` | | | +--------------------------------------------------+ WARNING: Cache 'HashInfo(name='md5', value='db4287e726604a63a231cf4462cb27df.dir', dir_info=None, size=497535926, nfiles=8818)' not found. File 'dataset' won't be created. ERROR: Checkout failed for following targets: dataset Is your cache up to date? ``` I tried searching for the solution in the given link but I could find it. Thanks in advance. ---

@htutlynn Can you post result of `dvc doctor` command? Also, `dvc checkout -v` could be helpful. I have a question: are you checking out your work on the same machine, or are you working on fresh clone of your repo? ---

@htutlynn And the project path is the same? If it is, can you verify that `{project_path}/.dvc/cache/db/4287e726604a63a231cf4462cb27df.dir` does not exist? ---

@Paffciu , I tried looking for `.dir` files but I could not find it. ![image](https://canada1.discourse-cdn.com/flex035/uploads/dataversioncontrol/original/1X/6a428a1b7847bb8bddb911ed1b291d6bbb1f58e9.png) Btw, after adding `dataset` dir with `dvc add dataset`, I manually added `dataset` dir to the project’s main `.gitignore` file before git commit instead of the command that’s got prompted after `dvc add dataset` command. I am not sure but I kinda doubt that it might be the reason. ---

@htutlyn it looks like the `dvc add` command has failed. Would it be possible for you to retry adding the dataset? Simplest verification that everything is allrigth would be: 1. `dvc add {data}` 2. `rm {data}` 3. `dvc checkout` Adding `{data}` to .gitignore manually should no influence the cache. ---

@Paffciu , I just did the steps all over again. Re-added the dataset by using `dvc add dataset` and then delete the `dataset` folder with `rm -rf dataset`. When I tried to redo `dvc checkout` on latest commit, ti works as expected but when I go the `initial dataset` commit, and tries `dvc checkout`, it doesn’t work. ---

@htutlynn I understand, was it done on your original repo - if so that does not change much because initial version of data had some problems adding. Would it be possible to retake all the steps, like: 1. creating new repo 2. adding initial version of data 3. `rm -rf` data 4. `dvc checkout` ? ---

HI @Paffciu, sorry for the late reply. Just like the steps that you described, I created everything from scratch and now it works as exactly as expected. As for the error, I think manually adding the `dataset` folder into the project’s main `.gitignore` caused the error. I didn’t include the step this time and now it works as expected without any errors. Thanks for the help. ---

@Paffciu , however when I try to do `dvc checkout` by going back to a former version of the dataset with git within a repo, cloned on a different machine, the error still persists. ---

@htutlynn did you run `dvc fetch` on this particular revision? In case of working with fresh repo clone, you need to update local cache by running either `dvc pull` or `dvc fetch`. `dvc pull` - you can simply think of it as `dvc fetch && dvc checkout` ---

@Paffciu , after pulling a fresh repo from github, I tried both approaches `dvc fetch` and `dvc pull`. After that, I go back to a former version of dataset and then used ‘dvc checkout’ but the error is still the same. ![image](https://canada1.discourse-cdn.com/flex035/uploads/dataversioncontrol/original/1X/d1febd7337f55f5242b792fa973e6087d22b8751.png) However, if I go back to a former dataset commit after pulling fresh repo without immediately dvc pulling or dvc fetching, and then do `dvc checkout` on that commit it works without that cache not found error. I am not sure if it is supposed to work that way or not. ---

@htutlynn that is because cache is downloaded for the current project version that is in repository. So, in order to download cache for older `data` version, you need first to `git checkout` its revision and only after that, use `dvc pull`. ---

@Paffciu , Oh, that makes everything clear. Thanks for the help!
