2. Cannot start mysql in linux via ``brew services start mysql``
|
|
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
|
|
use the following command instead:
|
|
|
|
``mysql.server start``
|
|
|
|
3. Every time I run ``snakemake -R download_dataset`` all rules are executed
|
|
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
|
|
This is expected behavior. The advantage of using ``snakemake`` under the hood is that every time a file containing data is modified every rule that depends on that file will be re-executed to update their results. In this case, since ``download_dataset`` updates all the raw data, and you are forcing the rule with the flag ``-R`` every single rule that depends on those raw files will be executed.

**Solution:**

|
Please make sure the sensors listed in SENSORS in ``config.yaml`` match your database tables.
