When running `snakemake -j1 -R pull_phone_data` or `./rapids -j1 -R pull_phone_data` all the rules and files are re-computed
|
|
|
|
???+ done "Solution"
|
|
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.

## How do I install RAPIDS on Ubuntu 16.04
|
|
|
|
???+ done "Solution"
|
|
1. Install dependencies (Homebrew - if not installed):
|
|
- `sudo apt-get install libmariadb-client-lgpl-dev libxml2-dev libssl-dev`
|
|
- Install [brew](https://docs.brew.sh/Homebrew-on-Linux) for linux and add the following line to `~/.bashrc`: `export PATH=$HOME/.linuxbrew/bin:$PATH`
|
|
- `source ~/.bashrc`
|
|
|
|
1. Install MySQL
|
|
- `brew install mysql`
|
|
- `brew services start mysql`
|
|
|
|
2. Install R, pandoc and rmarkdown:
|
|
- `brew install r`
|
|
- `brew install gcc@6` (needed due to this [bug](https://github.com/Homebrew/linuxbrew-core/issues/17812))
|
|
- `HOMEBREW_CC=gcc-6 brew install pandoc`
|
|
|
|
3. Install miniconda using these [instructions](https://docs.conda.io/projects/conda/en/latest/user-guide/install/linux.html)
|
|
|
|
4. Clone our repo:
|
|
- `git clone https://github.com/carissalow/rapids`
|
|
|
|
5. Create a python virtual environment:
|
|
- `cd rapids`
|
|
- `conda env create -f environment.yml -n MY_ENV_NAME`
|
|
- `conda activate MY_ENV_NAME`
|
|
|
|
6. Install R packages and virtual environment:
|
|
- `snakemake renv_install`
|
|
- `snakemake renv_init`
|
|
- `snakemake renv_restore`
|
|
|
|
This step could take several minutes to complete. Please be patient and let it run until completion.

## SSL connection error when running RAPIDS
|
|
|
|
???+ failure "Problem"
|
|
You are getting the following error message when running RAPIDS:
|
|
```bash
|
|
Error: Failed to connect: SSL connection error: error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol.
|
|
```

This is a bug in Ubuntu 20.04 when trying to connect to an old MySQL server with MySQL client 8.0. You should get the same error message if you try to connect from the command line. There you can add the option `--ssl-mode=DISABLED` but we can\'t do this from the R connector.
|
|
|
|
If you can\'t update your server, the quickest solution would be to import your database to another server or to a local environment. Alternatively, you could replace `mysql-client` and `libmysqlclient-dev` with `mariadb-client` and `libmariadbclient-dev` and reinstall renv. More info about this issue [here](https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1872541)

## `DB_TABLES` key not found
|
|
|
|
???+ failure "Problem"
|
|
If you get the following error `KeyError in line 43 of preprocessing.smk: 'PHONE_SENSORS'`, it means that the indentation of the key `[PHONE_SENSORS]` is not matching the other child elements of `PHONE_VALID_SENSED_BINS`
|
|
|
|
???+ done "Solution"
|
|
You need to add or remove any leading whitespaces as needed on that line.
|
|
|
|
```yaml
|
|
PHONE_VALID_SENSED_BINS:
|
|
COMPUTE: False # This flag is automatically ignored (set to True) if you are extracting PHONE_VALID_SENSED_DAYS or screen or Barnett's location features
|

This problem is due to the way `RMariaDB` handles a mismatch between data types in R and MySQL (see [this issue](https://github.com/r-dbi/RMariaDB/issues/121)). Since it seems this problem won't be handled by `RMariaDB`, you have two options:
|
|
|
|
1. Remove the the null character from the conflictive table cell(s). You can adapt the following query on a MySQL server 8.0 or older
|
|
```sql
|
|
update YOUR_TABLE set YOUR_COLUMN = regexp_replace(YOUR_COLUMN, '\0', '');
|
|
```
|
|
2. If it's not feasible to modify your data you can try swapping `RMariaDB` with `RMySQL`. Just have in mind you might have problems connecting to modern MySQL servers running in Linux:
|
|
- Add `RMySQL` to the renv environment by running the following command in a terminal open on RAPIDS root folder
|
|
```bash
|
|
R -e 'renv::install("RMySQL")'
|
|
```
|
|
- Go to `src/data/streams/pull_phone_data.R` or `src/data/streams/pull_fitbit_data.R` and replace `library(RMariaDB)` with `library(RMySQL)`
|
|
- In the same file(s) replace `dbEngine <- dbConnect(MariaDB(), default.file = "./.env", group = group)` with `dbEngine <- dbConnect(MySQL(), default.file = "./.env", group = group)`
|
|
## There is no package called `RMariaDB`
|
|
|
|
???+ failure "Problem"
|
|
You get the following error when executing RAPIDS:
|
|
```bash
|
|
Error in library(RMariaDB) : there is no package called 'RMariaDB'
|
|
Execution halted
|
|
```
|
|
|
|
???+ done "Solution"
|
|
In RAPIDS v0.1.0 we replaced `RMySQL` R package with `RMariaDB`, this error means your R virtual environment is out of date, to update it run `snakemake -j1 renv_restore`
|
|
|
|
## Unrecognized output timezone "America/New_York"
|
|
|
|
???+ failure "Problem"
|
|
When running RAPIDS with R 4.0.3 on MacOS on M1, lubridate may throw an error associated with the timezone.
|
|
```bash
|
|
Error in C_force_tz(time, tz = tzone, roll):
|
|
CCTZ: Unrecognized output timezone: "America/New_York"
|
|
Calls: get_timestamp_filter ... .parse_date_time -> .strptime -> force_tz -> C_force_tz
|
|
```
|
|
???+ done "Solution"
|
|
This is because R timezone library is not set. Please add `Sys.setenv(“TZDIR” = file.path(R.home(), “share”, “zoneinfo”))` to the file active.R in renv folder to set the timezone library. For further details on how to test if `TZDIR` is properly set, please refer to `https://github.com/tidyverse/lubridate/issues/928#issuecomment-720059233`.
|
|
|
|
## Unimplemented MAX_NO_FIELD_TYPES
|
|
|
|
???+ failure "Problem"
|
|
You get the following error when downloading Fitbit data:
|
|
```bash
|
|
Error: Unimplemented MAX_NO_FIELD_TYPES
|
|
Execution halted
|
|
```
|
|
???+ done "Solution"
|
|
At the moment RMariaDB [cannot handle](https://github.com/r-dbi/RMariaDB/issues/127) MySQL columns of JSON type. Change the type of your Fitbit data column to `longtext` (note that the content will not change and will still be a JSON object just interpreted as a string).

|
|
You get the following error when installing pandoc or running rapids:

As of Feb 2020 in M1 macs, R needs to be installed via brew under Rosetta (x86 arch) due to some incompatibility with selected R libraries. To do this, run your terminal [via Rosetta](https://www.youtube.com/watch?v=nv2ylxro7rM&t=138s), then proceed with the usual brew installation command. x86 homebrew should be installed in `/usr/local/bin/brew `, you can check which brew you are using by typing `which brew`. Then use x86 homebrew to install R and restore RAPIDS packages (`renv_restore`).
