Currently, mne.sys_info() requires the psutil package to list the total amount of installed memory. Unfortunately, psutil is not a core dependency, but only part of the [full] extras, which installs a large number of packages.
Since we probably don't want to promote psutil to a core dependency (it is not pure Python), what do you think of rolling our own solution? This could be as simple as:
import platform
import subprocess
def get_total_memory():
total_memory = "?"
if platform.system() == "Windows":
output = subprocess.check_output("systeminfo", shell=True).decode()
for line in output.splitlines():
if "Total Physical Memory" in line:
total_memory = int(line.split(":")[1].strip())
elif platform.system() == "Linux":
output = subprocess.check_output(["free", "-m"]).decode()
lines = output.splitlines()
mem_info = lines[1].split()
total_memory = int(mem_info[1])
elif platform.system() == "Darwin":
total_memory = int(
subprocess.check_output(["sysctl", "hw.memsize"])
.decode()
.split(":")[1]
.strip()
)
total_memory = int(total_memory / 1024**2)
return f"Total Memory: {total_memory} MB"
print(get_total_memory())I have only tested this on Linux so far (but I will run it on macOS and Windows soonish). WDYT?
