Kernel crashes when using fastparquet

Running the following code is known to have caused kernels to crash: dataframe.to_parquet()

Using pyarrow instead of fastparquet seems to have resolved this issue.

On a side note, when kernels crash, its most likely a package hasn't been installed correctly, hence re-installing the package would resolve the issue. It is also possible other dependent packages could cause the package to fall over, in such cases, its best to start out with a new environment. Finally, when using Conda environments, please avoid using pip to install packages, instead use conda install.
