|

|
||||
## Updating RAPIDS
|
||||
|
||||
To update RAPIDS, first pull and merge [origin]( https://github.com/carissalow/rapids), such as with:
|
||||
|
||||
```commandline
|
||||
git fetch --progress "origin" refs/heads/master
|
||||
git merge --no-ff origin/master
|
||||
```
|
||||
|
||||
Next, update the conda and R virtual environment.
|
||||
|
||||
```bash
|
||||
R -e 'renv::restore(repos = c(CRAN = "https://packagemanager.rstudio.com/all/__linux__/focal/latest"))'
|
||||
```
|
||||
|
||||
## Custom configuration
|
||||
### Credentials
|
||||
|
||||
As mentioned under [Database in RAPIDS documentation](https://www.rapids.science/1.6/snippets/database/), a `credentials.yaml` file is needed to connect to a database.
|
||||
It should contain:
|
||||
|
||||
```yaml
|
||||
PSQL_STRAW:
|
||||
database: staw
|
||||
host: 212.235.208.113
|
||||
password: password
|
||||
port: 5432
|
||||
user: staw_db
|
||||
```
|
||||
|
||||
where`password` needs to be specified as well.
|
||||
|
||||
## Possible installation issues
|
||||
### Missing dependencies for RPostgres
|
||||
|
||||
To install `RPostgres` R package (used to connect to the PostgreSQL database), an error might occur:
|
||||
|
||||
```text
|
||||
------------------------- ANTICONF ERROR ---------------------------
|
||||
Configuration failed because libpq was not found. Try installing:
|
||||
* deb: libpq-dev (Debian, Ubuntu, etc)
|
||||
* rpm: postgresql-devel (Fedora, EPEL)
|
||||
* rpm: postgreql8-devel, psstgresql92-devel, postgresql93-devel, or postgresql94-devel (Amazon Linux)
|
||||
* csw: postgresql_dev (Solaris)
|
||||
* brew: libpq (OSX)
|
||||
If libpq is already installed, check that either:
|
||||
(i) 'pkg-config' is in your PATH AND PKG_CONFIG_PATH contains a libpq.pc file; or
|
||||
(ii) 'pg_config' is in your PATH.
|
||||
If neither can detect , you can set INCLUDE_DIR
|
||||
and LIB_DIR manually via:
|
||||
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
|
||||
--------------------------[ ERROR MESSAGE ]----------------------------
|
||||
<stdin>:1:10: fatal error: libpq-fe.h: No such file or directory
|
||||
compilation terminated.
|
||||
```
|
||||
|
||||
The library requires `libpq` for compiling from source, so install accordingly.
|
||||
|
||||
### Timezone environment variable for tidyverse (relevant for WSL2)
|
||||
|
||||
One of the R packages, `tidyverse` might need access to the `TZ` environment variable during the installation.
|
||||
On Ubuntu 20.04 on WSL2 this triggers the following error:
|
||||
|
||||
```text
|
||||
> install.packages('tidyverse')
|
||||
|
||||
ERROR: configuration failed for package ‘xml2’
|
||||
System has not been booted with systemd as init system (PID 1). Can't operate.
|
||||
Failed to create bus connection: Host is down
|
||||
Warning in system("timedatectl", intern = TRUE) :
|
||||
running command 'timedatectl' had status 1
|
||||
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
|
||||
namespace ‘xml2’ 1.3.1 is already loaded, but >= 1.3.2 is required
|
||||
Calls: <Anonymous> ... namespaceImportFrom -> asNamespace -> loadNamespace
|
||||
Execution halted
|
||||
ERROR: lazy loading failed for package ‘tidyverse’
|
||||
```
|
||||
|
||||
This happens because WSL2 does not use the `timedatectl` service, which provides this variable.
|
||||
|
||||
```bash
|
||||
~$ timedatectl
|
||||
System has not been booted with systemd as init system (PID 1). Can't operate.
|
||||
Failed to create bus connection: Host is down
|
||||
```
|
||||
|
||||
and later
|
||||
|
||||
```bash
|
||||
Warning message:
|
||||
In system("timedatectl", intern = TRUE) :
|
||||
running command 'timedatectl' had status 1
|
||||
Execution halted
|
||||
```
|
||||
|
||||
This can be amended by setting the environment variable manually before attempting to install `tidyverse`:
|
||||
|
||||
```bash
|
||||
export TZ='Europe/Ljubljana'
|
||||
```
|
||||
|
||||
Note: if this is needed to avoid runtime issues, you need to either define this environment variable in each new terminal window or (better) define it in your `~/.bashrc` or `~/.bash_profile`.
|
||||
|
||||
## Possible runtime issues
|
||||
### Unix end of line characters
|
||||
|
||||
Upon running rapids, an error might occur:
|
||||
|
||||
```bash
|
||||
/usr/bin/env: ‘python3\r’: No such file or directory
|
||||
```
|
||||
|
||||
This is due to Windows style end of line characters.
|
||||
To amend this, I added a `.gitattributes` files to force `git` to checkout `rapids` using Unix EOL characters.
|
||||
If this still fails, `dos2unix` can be used to change them.
|
||||
|
||||
### System has not been booted with systemd as init system (PID 1)
|
||||
|
||||
See [the installation issue above](#Timezone-environment-variable-for-tidyverse-(relevant-for-WSL2)).
