Error running the generate_petastorm_dataset example #583

Closed ghost closed 4 years ago

ghost commented 4 years ago

I followed the instructions of the installation and tried the example from petastorm/examples/hello_world/petastorm_dataset/generate_petastorm_dataset.py At first i got this error: "Failed to locate the winutils binary in the hadoop binary path" To solve this i downloaded hadoop and set the System Environment Variable to the folder. And this did solve the error, however there is another error which i don't quite understand.

The files at FILENAME_temporary\0_temporary\attempt_... are generated and sometimes i get an additional error that those cannot be deleted.

Is this a known problem? Are there solutions to it or did i maybe missed some step during installation?

Petastorm is officially supported only on Linux os. We never tried to make it work on Windows - perhaps it's possible to make it work, however, this is not part of our plans at the moment.
